The CARMENES spectrograph present on the 3.5m telescope in Calar Alto Observatory (Almería) and the HARPS-N spectrograph on the National Galileo Telescope (TNG) in the Roque de Los Muchachos Observatory have helped the team from the Instituto de Astrofísica de Canarias (IAC) make a combination of the observations. They were able to reveal some new data about the extrasolar planet that had a surface temperature of approximately 2000 K. The extrasolar planet named MASCARA-2B/KELT-20b is like an ultra hot Jupiter. This can be categorized into a completely new group of exoplanets. It is the hottest one to be known until now. The rationale behind its high temperature is the closeness of its orbit to its host star, which causes it to collect a large flux of radiation in the topmost layers of its atmosphere.
Núria Casasayas of IAC researcher led the team which had earlier in 2018 already made the initial measurements of the atmosphere and studied the planet at the time of four transits. The use of two telescopes helped the researchers gather more of data on the new exoplanet. The different wavelengths regions of the telescopes helped provide a wider spectral range. The singly ionized magnesium and iron plus hydrogen beta data were obtained using HARPS-N while the ionized calcium’s presence was detected using CARMENES. And both the instruments together helped identify neutral sodium and hydrogen alpha.
The researchers are focusing more on the exoplanetary atmospheres now. The high-resolution spectroscopy performing instruments permit the discovery of the atmospheric composition of planets beyond the Solar System and also to measure other vital parameters including the layers’ temperatures where their elements are found, and various factors of the dynamics of the atmosphere. The Calar Alto Observatory is the largest astronomical complex in Europe. It has signed a contract with the firm Azimuth to start a program that will permit citizens to enter the observatory and use facilities and instruments that were till date available to professionals.
