Astronomers looking over data from the Transiting Exoplanet Survey Satellite ( TESS ) recently came across something uncanny : an object called TIC 400799224 has been fluctuate in cleverness , like a ace being routinely eclipsed . Their depth psychology of the observations suggest that TIC 400799224 is actually two stars , one of which is being orb by a mystery object . The researchers distrust that a enceinte asteroid or perhaps even a small planet is release rubble cloud that dim the starlight from TESS ’s view .
launch in 2018,TESSis task with find exoplanets — human beings beyond our solar system — that pass in front of their host star topology , have detectable dips in the star ’s brightness . So far , TESS has discovered 172 exoplanets , and 4,703 prospect exoplanets await more analysis . These alien worldly concern aid planetary scientists realize the demography of the universe and the multifariousness of planet that exist .
TIC 400799224 seems to be a stellar binary , or two stars orbiting one another . The stars are thought to be about 300 AU apart , allot to the paper , with 1 AU being the middling space between Earth and the Sun . The research team is still not certain which star hosts the secret object that causes the brightness dips . The dimming happens about every 19.77 days , but the distance , intensity , and form of the dips vary a portion .

The cyclicity of the dimming is what lead the squad to believe it ’s due to an orb target , though the dips do n’t happen with every transit , so the team consider the most likely culprit is a sporadically emitted dust cloud . Their research ispublishedin The Astronomical Journal .
What makes TIC 400799224 particularly odd is that the suspect rubble clouds are large than researchers would anticipate , assuming that the clouds are due to the object ’s disintegration over time . As a Center for Astrophysics | Harvard & Smithsonianpress releasenotes , slow dissolution is the cause of the dust clouds that come off Ceres , a nanus planet in our solar system .
Othersuspecteddisintegratingobjects have also been find , so TIC 400799224 has some case in point . The researchers will continue to study the system and review historical record of TIC 400799224 ’s light , in hopes of better see what ’s going on out there .
