NASA first saw ‘living’ planet embracing a white dwarf star


NASA’s Transiting Exoplanet Survey Satellite (TESS) and the Space Agency’s retired Spitzer Space Telescope have been used to possibly “survivor” the planet to embrace the white dwarf star.

White dwarfs are those who exhaust their nuclear fuel once they become stars.

In a statement, NASA explains, “A Jupiter-shaped object called WD 1856B is about seven times larger than a white dwarf.” “It resolves this stellar cycle every 34 hours, which is 60 times faster than the orbits of our Sun.”

“WD 1856B somehow managed to get close to its white dwarf and managed to live in one piece,” said Andrew Vanderburg, a NASA Sagan Fellow at UT Austin while completing research And is now an assistant professor at the university. Of Wisconsin-Madison. “The white dwarf formation process destroys nearby planets, and anything that gets too close later is usually burst by the star’s enormous gravity. We still have many questions about what WD 1856 b Kind of arrived at his current location without a date. ”

WD 1856 + 534 is stated to be 40% larger than Earth.

“We have known for a long time that after white dwarfs are born, distant small objects like asteroids and comets can disintegrate inward toward these stars. They are usually separated by the strong gravity of a white dwarf and turn into a disk of debris, ”said co-author Siyi Xu, in the statement, an assistant astronomer at the International Gemini Observatory in Hilo, Hawaii. “That’s why I was so excited when Andrew told me about this system. We’ve seen signs that the planets can also shatter inwards, but this seems to be the first time we’ve seen a planet that has Has made the entire journey intact. ”

Experts from UT Austin and Caltech also participated in the work.

NASA’s wealth of space hardware keeps shining new light on distant stars. In a separate project, scientists recently used data from NASA’s Kepler Space Telescope to discover a “vampire” star “sucking up” that is ejecting life from another star.

Experts discovered a surprising “super-outburst” from a dwarf nova, a type of “cataclysmic variable star”. According to NASA, the star system, which consists of a white dwarf star and its much smaller brown dwarf companion, was brightened by a factor of 1,600 in less than a day. It then slowly faded away.
