Mass loss predictions for Subdwarf B stars [PDF]
Astrophysics and Space Science, 2003 We present the results of Monte Carlo mass-loss predictions for hot low-mass stars, specifically for Subdwarf B (SdB) stars. It is shown that the mass-loss rates on the Horizontal Branch (HB) computed from radiative line-driven wind models are not high ...

Asteroseismology of hot B subdwarf stars [PDF]
EPJ Web of Conferences, 2013 Non-radial pulsations in Extreme Horizontal Branch stars (also known as hot B subdwarfs or sdB stars) offer strong opportunities to study, through asteroseismology, the structure and internal dynamics of stars in this intermediate stage of stellar ...

On the 3He anomaly in hot subdwarf B stars
Open Astronomy, 2017 Decades ago, 3He isotope enrichment in helium-weak B-type main-sequence, in blue horizontal branch and in hot subdwarf B (sdB) stars, i.e., helium-core burning stars of the extreme horizontal branch, were discovered. Diffusion processes in the atmosphere

Tidal Spin-up of Subdwarf B Stars
The Astrophysical JournalHot subdwarf B (sdB) stars are stripped helium-burning stars that are often found in close binaries, where they experience strong tidal interactions. The dissipation of tidally excited gravity waves alters their rotational evolution throughout the sdB ...

Stark Widths of Ar II Spectral Lines in the Atmospheres of Subdwarf B Stars
Atoms, 2017 Stark broadening parameters are of interest for many problems in astrophysics and laboratory plasmas investigation. Ar II spectral lines are observed in many kinds of stellar atmospheres such as the atmospheres of B-Type stars and subdwarf B stars.

Hot subdwarf stars in close-up view [PDF]
Astronomy and Astrophysics, 2013 Context: Hot subdwarf B stars (sdBs) are considered to be core helium-burning stars with very thin hydrogen envelopes situated on or near the extreme horizontal branch (EHB). The formation of sdBs is still unclear as well as the chemical composition of their atmospheres. The observed helium depletion is attributed to atmospheric diffusion.

Hot subdwarf stars in close-up view - II. Rotational properties of single and wide binary subdwarf B stars [PDF]
Astronomy & Astrophysics, 2012 Subluminous B stars (sdBs) form the extremely hot end of the horizontal branch and are therefore related to the blue horizontal branch (BHB) stars. While the rotational properties of BHB stars have been investigated extensively, studies of sdB stars have
