Thai astronomers have discovered a gas giant planet called HAT-P-37b with thick clouds similar to Jupiter.


NARIT National Astronomical Research Institute Thai astronomers jointly with the HAT-P-37b system at the Sierra Remote Observatory in the US have revealed that they have detected the expected signal from a new planet. It is a gas giant planet similar to Jupiter.

Supachai Aviphan Dr – Narit researchers, National Tsing Hua University researchers from Taiwan, and an international network of astronomers are using the National Astronomical Research Institute’s 0.7-meter automatic telescope. (public organization) at the Sierra Remote Observatory in the USA and telescopes in a worldwide network. It studied the transit of the gas giant Jupiter-like planet (HAT-P-37b) for more than seven years until it detected an expected signal from a new planet in the system. It also found that the atmosphere of the planet HAT-P-37b is so thick with clouds that light cannot pass through.


Planet HAT-P-37b It is a Jupiter-like gas giant with 1.1 times the mass of Jupiter and 1.1 times the radius of Jupiter. It is a planet with a duration of only 2.8 days. Its surface temperature is estimated to be as high as 1,200 K. Most astronomers study exoplanets. Using the transit method, the dimming of the parent star is measured when a planet passes in front of it. A study of planetary transit signals HAT-P-37b between 2014 and 2021 found that the timing of the transit phenomenon changed. This may be caused by another object that has not yet been discovered in that system. The transit time change signal is about 1.74 minutes, with an orbital period of about 3.3 years, and if the object has an orbital period twice the planetary period of HAT-P-37b, the object could be a minor planet, about 0.06 times the mass. However, confirmation of the existence of such planets will require further observations in the future.

The planet’s atmosphere was also studied using the transmission spectra technique. (transmission spectrum) found that thick clouds block light from shining through. Currently, the study of the atmospheres of exo-solar planets. Still less than 100, the discovery gives astronomers a better understanding of the formation of the atmospheres of extrasolar planets.

The research used a global network of medium to small telescopes. The potential of such telescopes in extrasolar studies is demonstrated, including the 0.7 m automatic telescope at the Sierra Remote Observatory in the US (https://www.narit.or.th/index.php/telescope/trt) for the study. The planets can also work together as an international research network The use of medium to small telescopes, although not as powerful as large telescopes, has become more and more widespread around the world. This makes it easy for astronomers to use. It helps to find new knowledge. Astronomy will increase in the future.
