The space is full of various secrets and mysteries. The more you dig it, the more it reveals to you. Various countries all over the world are keen on observing the space affairs with the help of their respective space research institutes such as NASA (U.S.), ISRO (India), ROSCOSMOS (Russia) and many others. These institutes study and observe space for presenting the research about stars, asteroids, planets, solar system as well as some more interesting and mysterious space objects such as expolanets and interstellar space bodies.
Recently, NASA’s Transiting Exoplanet Survey Satellite (TESS) — a telescope for Explorers program, NASA — has revealed a seemingly unbelievable planet. The team led by Tiago Campante — researcher, Faculdade de Ciências da Universidade do Porto and Instituto de Astrofísica e Ciências do Espaço (IA) — observed two huge red stars, namely HD 203949 and HD 212771. As a result f a thorough study based o their observations, the team concluded that one of the stars might be an improbable planet.
The crew detected oscillations in old exoplanet-host stars with the help of TESS. The research was published in the Astrophysical Journal in a form of an article. The team carried out the research with the help of asteroseismology. Through asteroseismology, the researchers recorded the observations about mass, age, size and other physical properties of both the stars. By studying the evolutionary state of one of the stars — HD 203949 — the researches tried to reveal facts about avoiding engulfment by its planets.
Tiago stated that they were able to measure the gentle pulsations present at the surface of these stars more precisely with the help of TESS observations. According to Vardan Adibekyan — co-author, Universidade do Porto and IA — the study demonstrates the linking of exoplanetary and stellar astrophysics perfectly. exoplanetary analysis helps in detecting presence of a plant whereas stellar one is used to determine the evolutionary states of a star.
