NEWARK, Del.--(BUSINESS WIRE)--Aug 8, 2023--

Astronomers have found a planetary system with six different worlds that orbit in a strange rhythm. The set of planets move around their star in a rhythmic beat, scientists say, staying synchronised in a kind of dance. The findings could help shed more light on how planets form and evolve, the researchers say. The star is smaller, and slightly dimmer than the Sun, and the six “sub-Neptunes” - possibly smaller versions of Neptune in our solar system - move in a cyclic rhythm. According to the experts, this orbital waltz repeats itself so precisely it can be readily set to music. The star, HD110067, is 100 light-years away in the northern constellation of Coma Berenices, and had perplexed researchers for years. Now scientists, including those at the University of Warwick, have revealed the true architecture of this unusual system using Nasa and European Space Agency (Esa) spacecraft. The analysis was led by University of Chicago scientist Dr Rafael Luque, who said: “This discovery is going to become a benchmark system to study how sub-Neptunes, the most common type of planets outside of the solar system, form, evolve, what are they made of, and if they possess the right conditions to support the existence of liquid water in their surfaces.” The first indication of planets orbiting the strange star system came in 2020, when Nasa’s Transiting Exoplanet Survey Satellite (Tess) detected dips in the star’s brightness which suggested planets were passing in between the star and the spacecraft. A preliminary analysis revealed two possible planets - one with a year (the length of time it takes to complete one orbit around the star) of 5.64 days, and another with an unknown period at the time. Two years later, Tess observed the same star again, and analysis ruled out the original interpretation but presented two additional possible planets. Much was still unknown about the planetary system, until scientists across the world - including those at the University of Warwick - joined the investigation. They used data from Esa’s Characterising Exoplanet Satellite (Cheops), hoping to determine the orbital periods of these faraway planets. While multi-planet systems are common in the Milky Way, those in a tight gravitational formation known as “resonance” are observed by astronomers far less often. In this case, the planet closest to the star makes three orbits for every two of the next planet out - called a 3/2 resonance - a pattern that is repeated among the four closest planets. Among the outermost planets, a pattern of four orbits for every three of the next planet out (a 4/3 resonance) is repeated twice. Thomas Wilson, from the Department of Physics at the University of Warwick, said: “By establishing this pattern of planet orbits, we were able to predict other orbits of planets we hadn’t yet detected. “From this we lined up previously unexplained dips in starlight observed by Cheops and discovered three additional planets with longer orbits. This was only possible with the crucial Cheops data.” Researchers say the planets - two to three times the size of Earth - are likely to have been performing this same rhythmic dance since the system formed billions of years ago. Dr Luque said: “We think only about 1% of all systems stay in resonance, and even fewer show a chain of planets in such configuration.” Experts say orbitally resonant systems are extremely important to find because they tell astronomers about the formation and subsequent evolution of the planetary system. Planets around stars tend to form in resonance but can easily have their orbits thrown around. For example, a very massive planet, a close encounter with a passing star, or a giant impact event can all disrupt the careful balance. Therefore, multi-planet systems preserving their resonance are rare. HD110067 is the brightest known system with four or more planets. Since those planets are all sub-Neptune-sized with likely larger atmospheres, it makes them ideal candidates for studying using the James Webb Space Telescope (JWST) and the Esa’s future Ariel telescope. Mr Wilson added: “All of these planets have large atmospheres - similar to Uranus or Neptune - which makes them perfect for observation with JWST. “It would be fascinating to test if these planets are rocky like Earth or Venus but with larger atmospheres - solid surfaces potentially with water. “However, they are all much hotter than Earth - 170C to 530C - which would make it very difficult for life to exist.” Hannah Osborne, a PhD student at UCL’s Mullard Space Science Laboratory and a co-author of the study, said: “The system itself is a key discovery for exoplanet science: because all six planets are in a resonant chain we know that the architecture of the system can’t have changed much since its formation, so by studying HD110067 we get a rare window into the past to understand how these types of systems may have formed and evolved.” The findings are published in the Nature journal.

A military takeover of Taiwan is likely, according to one of many Chinese government-approved artificial intelligencechatbots that seem to toe the ruling Communist Party’s official line. The island nation has been a self-governing democracy since its separation from the mainland following a civil war in 1949, but China has claimed it as part of its national territory. The chatbots have dubbed Taiwan an inseparable part of China. The Chinese government recently approved a number of AI chatbots for use in the country, including a bot named Ernie and developed by tech giant Baidu and TikTok owner ByteDance’s Doubao. When Bloomberg tested some of these AI services for how government oversight affected the accuracy of information provided by these chatbots, it found they appeared to be trained to follow the ruling Communist Party’s line. When asked whether Taiwan is a country, all the tested chatbots reportedly said the self-governed island was a part of China, and Baidu’s Ernie chatbot reportedly said a Chinese military takeover of Taiwan is likely. The Zhipu chatbot described China’s current economic situation, which experts said is at one of its weakest points in recent decades, to be “a mix of joys and sorrows”, reported Bloomberg. Another chatbot, SenseTime, reportedly described the economy as “very stable”. When asked to respond queries that may be deemed “sensitive content”, the Ernie bot was found to “change the subject”, while Zhipu would delete its response if it found it to be “controversial”, according to the report. Such generative AI tools are trained by analysing large quantities of data to respond to user queries with unique human-like replies. For instance, OpenAI’s ChatGPT has demonstrated a wide range of abilities, from summarising complex research, answering logical questions and also cracking business and medical school exams deemed crucial for students to pass. A number of Chinese companies have sought to build their own version of AI chatbots, prompting China’s cyberspace regulator to release ground rules for companies developing generative AI services. But prior to the launch of these chatbots, the Chinese government made several months-long efforts to regulate the generative AI industry. Some of the proposed rules have sought to ensure the content of Chinese AI systems reflect “socialist core values” and avoid information undermining “state power” or “national unity”. Baidu’s launch of Ernie for full public use on Thursday led to the company’s stock price rising by over 3 per cent following the announcement. Other AI firms such as Baichuan and Zhipu AI also launched their ChatGPT-like large language models on Thursday. The ruling Communist Party issued regulations on 15 August that required tech companies to carry out a security review of their chatbots, and obtain approvals before their products are publicly launched. It also requires companies providing such AI services to comply with government data requests, regulations which are currently absent in the US.
