"We're finding the oldest stellar remnants in the Milky Way that are polluted by once Earth-like planets,", lead author of the study, a Ph.D. student at the department of physics, University of Warwick.
They are so common in the universe—97 percent of all stars will eventually become one—making it crucial to comprehend them. In order to determine how long the "red" star WDJ2147-4035 has been cooling, astronomers used spectroscopic and photometric data from GAIA, the Dark Energy Survey, and the X-Shooter instrument at the European Southern Observatory.
"This is a very interesting white dwarf as its ultra-cool surface temperature, the metals polluting it, its old age, and the fact that it is magnetic, makes it extremely rare."
