A White Dwarf Catalog from LAMOST DR11 Using Deep Learning
The Astrophysical Journal Supplement SeriesWhite dwarfs, also referred to as degenerate dwarfs, represent the ultimate fate for the majority of stars in the Universe, unless their mass is large enough for them to evolve into black holes or neutron stars.

The Astronomical Journal, 2023 Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with Keck/MOSFIRE, Gemini/GNIRS, and Gemini/Flamingos-2 of seven white dwarfs ...

Spitzer White Dwarf Planet Limits [PDF]
, 2006 We present preliminary limits on the presence of planets around white dwarf stars using the IRAC photometer on the Spitzer space telescope. Planets emit strongly in the mid-infrared which allows their presence to be detected as an excess at these ...

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs
The Anatomical Record, EarlyView.Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...

Stability of the r-modes in white dwarf stars [PDF]
, 1999 Stability of the r-modes in rapidly rotating white dwarf stars is investigated. Improved estimates of the growth times of the gravitational-radiation driven instability in the r-modes of the observed DQ Her objects are found to be longer (probably ...

Orbital motion detected in γ Cas Fe K emission lines
Astronomy & AstrophysicsA subset of Be stars, typified by the naked-eye star γ Cas, exhibits unusually bright and hard X-ray emission, the origin of which has remained debated for five decades.

Know Your Neighborhood: A Detailed Model Atmosphere Analysis of Nearby White Dwarfs
, 2012 We present improved atmospheric parameters of nearby white dwarfs lying within 20 pc of the Sun. The aim of the current study is to obtain the best statistical model of the least-biased sample of the white dwarf population.
