[2412.02694] Increased Surface Temperatures of Habitable White Dwarf ...
2024年12月3日 · We present simulations of an aqua planet with an Earth-like atmospheric composition and incident stellar insolation orbiting in the habitable zone of two different types of stars - a 5000 K white dwarf and main-sequence K-dwarf star Kepler-62 with a similar effective temperature - and identify the mechanisms responsible for the two differing ...
White dwarf - Wikipedia
Sirius B, which is a white dwarf, can be seen as a faint point of light to the lower left of the much brighter Sirius A. ... The merger process of two co-orbiting white dwarfs produces gravitational waves. If a white dwarf is in a binary star system and is accreting matter from its companion, a variety of phenomena may occur, including novae ...
White Dwarfs Could Have Habitable Planets, Detectable by JWST
2024年12月3日 · More than a dozen planets have been discovered orbiting white dwarf stars. That’s a small fraction of the known exoplanets, but it tells us that planets can survive the red giant stage of a...
The Fate of Oceans on First-Generation Planets Orbiting White Dwarfs
2024年12月17日 · Abstract: Several groups have recently suggested that small planets orbiting very closely around white dwarf stars could be promising locations for life to arise, even after stellar death. There are still many uncertainties, however, …
Potential for Life to Exist and be Detected on Earth-like Planets ...
2024年12月12日 · With recent observations confirming exoplanets orbiting white dwarfs, there is growing interest in exploring and quantifying the habitability of temperate rocky planets around white dwarfs.
Discovery of Nearest Candidate Exoplanet Orbiting a White Dwarf
2024年9月25日 · Researchers have discovered a handful of exoplanets around white dwarfs already — what makes this discovery special? WD 0310–688 is only 34 light-years away, making it the closest white dwarf with a planet candidate, and no planet has ever been discovered 0.1–2 au from a white dwarf.
How alien life could arise on planets orbiting white dwarfs | Space
2024年6月18日 · A planet orbiting one of these exotic objects would need to be about 930,000 miles (1.5 million kilometers) from the white dwarf — about 1% of the distance from Earth to the sun — to be warm...
Potential For Life To Exist And Be Detected On Earth-like Planets ...
2024年12月2日 · With recent observations confirming exoplanets orbiting white dwarfs, there is growing interest in exploring and quantifying the habitability of temperate rocky planets around white dwarfs.
James Webb telescope makes ultra-rare detection of 2 planets orbiting …
2024年2月6日 · The James Webb Space Telescope has detected two alien planets orbiting white dwarfs, the collapsed husks of once-mighty stars. The discovery offers a hint of what our solar system will look...
The Fate of Oceans on First-Generation Planets Orbiting White Dwarfs
2024年12月16日 · In order for water to persist on the surfaces of planets orbiting white dwarfs, the water must first survive the AGB phase of stellar evolution, then avoid being lost due to photoevaporation due to X-ray and extreme ultraviolet (XUV) radiation from the newly-formed white dwarf, and then finally survive the tidal migration of the planet inwards ...
