Spectral evolution of hot hybrid white dwarfs: II. Photometry
Semih Filiz, Nicole Reindl, David Jones +4
We present a photometric analysis of 19 DA and 13 DAO white dwarfs (WDs) with effective temperatures exceeding 60 kK, building on the spectral analysis reported in the first paper…
The massive hot subdwarf binary LAMOST J065816.72+094343.1
F. Mattig, B. N. Barlow, D. Liu +9
Massive short-period binaries involving hot subdwarf stars (sdO/Bs) are rare but important to constraining pathways for binary star evolution. Moreover, some of the most promising…
The twin red giant branch system BD+20 5391 A case study of low-mass double-core evolution
M. Kurpas, M. Dorsch, S. Geier +12
Understanding interactions of binary systems on the red giant branch is crucial to understanding the formation of compact stellar remnants such as helium-core white dwarfs (He-WDs)…
Where are the binaries? -- Searching for blue horizontal-branch stars in binary systems in the inner Galactic Halo
R. Culpan, M. Dorsch, I. Pelisoli +14
Blue horizontal-branch (BHB) stars are evolved low-mass objects that have completed their core hydrogen burning main-sequence (MS) stage and have lost significant mass during the r…
The binary fraction of Blue Horizontal-Branch (BHB) Stars
Yanjun Guo, Kun Chen, Zhenwei Li +6
Blue horizontal-branch (BHB) stars are old, low-mass, metal-poor stars that serve as important tracers of the Galactic halo structure, kinematics, and evolution.Understanding their…
How an overweight and rapidly rotating PG 1159 star in the Galactic halo challenges evolutionary models
Nina Mackensen, Nicole Reindl, Klaus Werner +2
PG 1159 stars are thought to be progenitors of the majority of H-deficient white dwarfs. Their unusual He-, C-, and O-dominated surface composition is typically believed to result…
