The discovery of the first transiting giant planet orbiting a white dwarf (WD 1856+534b) was also announced today in a separate paper & proves the existence of planets around white dwarfs. @KalteneggerLisa was a co-author on this paper.https://www.youtube.com/watch?v=fDhG0ppvQ2g&feature=youtu.be …
“We know now that giant planets can exist around white dwarfs, & evidence stretches back over 100 years showing rocky material polluting light from white dwarfs." Dr. Ryan MacDonald (@MartianColonist, research associate in astronomy at @Cornell & @CSInst fellow)
"There are certainly small rocks in white dwarf systems. It’s a logical leap to imagine a rocky planet like the Earth orbiting a white dwarf.” Dr. Ryan MacDonald (@MartianColonist, postdoc in astronomy at @Cornell & @CSInst fellow)pic.twitter.com/riVme8g69P
NASA’s @NASA_TESS is now looking for such rocky planets around white dwarfs. If and when one of these worlds is found, @KalteneggerLisa & her team have developed the models & tools to identify signs of life in their atmospheres. The Webb telescope could soon begin this search.pic.twitter.com/z4f4sNc9Ix
“Could life go on, even once our sun has died? Signs of life on planets orbiting white dwarfs would not only show the incredible tenacity of life, but perhaps also a glimpse into our future.” Lisa Kaltenegger (@KalteneggerLisa, director of the Carl Sagan Institute @CSInst)pic.twitter.com/8Pilj00ZDu
The paper, 'The White Dwarf Opportunity' will appear on arXiv tonight. http://doi.org/10.3847/2041-8213/aba9d3 …pic.twitter.com/ocjFNhj4VX
***Live Stream Alert***
There will be a live stream with @CSInst fellows this Sunday Sept 20th. Stay tuned for more details!
Topics: The exciting discovery of the 1st white dwarf exoplanet & the prospects for finding life around Earth-like planets orbiting white dwarfs
**** Upcoming Video Alert*****
Tomorrow we will be releasing a video featuring @CSInst fellows discussing their paper on how the JWST may find signatures of life on Earth-like planets orbiting white dwarfs
