Presupernova evolution of accreting white dwarfs with rotation
, 2004 We discuss the effects of rotation on the evolution of accreting carbon-oxygen white dwarfs, with the emphasis on possible consequences in Type Ia supernova (SN Ia) progenitors.

An unusual white dwarf star may be a surviving remnant of a subluminous Type Ia supernova [PDF]
Science, 2017 Unusual star may be supernova debris Type Ia supernovae occur when a white dwarf star is completely destroyed in a thermonuclear explosion. Recently, another class of supernova has been found, dubbed type Iax; these look like type Ia but are much fainter

The Post-Common Envelope and Pre-Cataclysmic Binary PG 1224+309 [PDF]
, 1998 We have made extensive spectroscopic and photometric observations of PG 1224+309, a close binary containing a DA white dwarf primary and an M4+ secondary. The H alpha line is in emission due to irradiation of the M-star by the hot white dwarf and is seen

Advanced Photonics Research, EarlyView.The necessity and feasibility of enhancing light outcoupling in perovskite light‐emitting diodes (PeLEDs) is highlighted. On near‐IR PeLEDs, low‐cost, micro‐textured light management (LM) foils demonstrate boost in light extraction. Optimizing perovskite thickness and the optical cavity in synergy with LM foils is crucial for maximizing performance ...

White Dwarf Cooling Curves and Searches For White Dwarfs [PDF]
Highlights of Astronomy, 1998 White dwarf (WD) evolution is essentially a cooling problem in two parts. Degenerate electrons in the core provide the support while non-degenerate C and O ions provide the thermal reservoir (Koester & Chanmugam 1990, Kawaler 1996). The rate of energy loss through the non-degenerate envelope of H and He—segregated by gravitational settling—is ...
