Mein herzliches Dankeschön an einen Kunstliebhaber aus Oldenburg für den Kauf eines Leinwanddruckes meines handgemalten Acrylgemäldes 'Pinkfarbene Katze und oranger Vogel'. Möge das Bild viele Jahre viel Freude bereiten.
We’re back with a session on planets around white dwarfs 🪐
Ryan MacDonald reminds us that in a very long time this will be the fate of our sun too. Jupiter and Saturn will probably fine but closer in… nah likely not.
This is basically what we can test by looking at white dwarf planetary systems. Killing planets in this way means there are polluted white dwarfs with planetary material in their stellar atmosphere. But for the ones that survive we can do a study of what could be.
The next talk is by Andrew Vanderburg on #MEOW: a survey targeting white dwarf systems to study the prognosis of the solar system.
Mars might survive, but be roasted. The smaller gravity after the red giant phase will push the orbits further out. See pictures for a graphics.
Combining data from TESS and JWST, they’ve found one close-in TESS planet around a WD, and even after searching 10000 more, they cannot find another one; so this is rare!
