Horizontal branch stars: the interplay between observations and theory, and insights into the formation of the Galaxy

M Catelan - Astrophysics and Space Science, 2009 - Springer
We review and discuss horizontal branch (HB) stars in a broad astrophysical context,
including both variable and non-variable stars. A reassessment of the Oosterhoff dichotomy …

Spectra of type Ia supernovae from double degenerate mergers

CL Fryer, AJ Ruiter, K Belczynski… - The Astrophysical …, 2010 - iopscience.iop.org
The merger of two white dwarfs (aka double-degenerate merger) has often been cited as a
potential progenitor of Type Ia supernovae. Here we combine population synthesis, merger …

Pulsation versus metallicism in Am stars as revealed by LAMOST and WASP

B Smalley, V Antoci, DL Holdsworth… - Monthly Notices of …, 2017 - academic.oup.com
We present the results of a study of a large sample of A and Am stars with spectral types
