ZTF J1901+1458 (nicknamed Z; formally ZTF J190132.9+145808.7; Gaia ID 4506869128279648512 [1]) is a white dwarf, about 135 light years away roughly in the direction of Epsilon Aquilae, discovered by the Zwicky Transient Facility circa 2021.
An exoplanet orbits PSR B1620-26 and its white dwarf companion (see below) in a circumbinary orbit. HD 49798: 1,600 White dwarf: One of the smallest white dwarf stars known. [15] ZTF J1901+1458: 1,809 Currently the most massive white dwarf known. [16] Janus: 3,400 A white dwarf with a side of hydrogen and another side of helium. [17] Wolf 1130 ...
White dwarfs with hydrogen-poor atmospheres, such as WD J2147–4035, are less affected by CIA and therefore have a yellow to orange color. [80] [77] The white dwarf cooling sequence seen by ESA's Gaia mission. White dwarf core material is a completely ionized plasma – a mixture of nuclei and electrons – that is
About 97% of all stars are destined to become white dwarfs when they die," Caiazzo said. "Our sun, for example, is currently burning hydrogen into helium in its core.
And now, right before the second one could end its stellar life cycle and become a white dwarf in the way that stars normally do - by evolving into a type of star called a red giant - the leftover ...
This white dwarf started its life as a star about twice the sun's mass, living a lifespan of perhaps 1.2 billion years before entering its death throes. Many white dwarfs have a debris disk ...
