PASADENA, Calf. — (PASADENA, Calf.) -- A Jupiter-sized planet was the main course for a dying star's meal, according to scientists who witnessed this rare interstellar course.
A study published Wednesday in"Nature," detailed the observations and analysis of the event that took place on May 20, 2020. Kishalay De, a postdoc at MIT's Kavli Institute for Astrophysics and Space Research, and the lead author of the study, said the gaseous planet spiraled close into the star's orbit until it was engulfed into its core.
It took another year for De and his team to determine what caused the change in brightness that was observed. He analyzed data from the Keck Observatory in Hawaii, which also observed the event. The team got more data from the Palomar Observatory which used an infrared camera to observe the event and it showed"signals of colder material, in contrast to the white-hot, optical emissions that arise from binaries and other extreme stellar events."
More data found that the dying star threw out colder energy for over a year. De said the data showed that the energy was about 1000 times smaller than the star, which was a key breakthrough.
