New self-consistent wind parameters fitting optical spectra of O-type stars observed with HERMES spectrograph
Alex C. Gormaz-Matamala, Michel Curé, Alex Lobel +5
We perform spectral fitting for a set of O-type stars based on self-consistent wind solutions, which provide mass-loss rate and velocity profiles directly derived from the initial…
Open clusters: III. Fundamental parameters of B stars in NGC 6087, NGC 6250, NGC 6383 and NGC 6530. B type stars with circumstellar envelopes
Y. Aidelman, L. S. Cidale, J. Zorec +1
Context. Stellar physical properties of star clusters are poorly known. Aims. Our goals are to perform a spectrophotometric study of the B star population in open clusters to deriv…
A deep and wide-field view at the IC 2944 / 2948 complex in Centaurus
G. Baume, M. J. Rodríguez, M. A. Corti +2
We employed the ESO MPI wide-field camera and obtained deep images in the VIc pass-bands in the region of the IC 2944/2948 complex (l ~ 294; b ~ -1), and complemented them with lit…
The Discovery of Binary White Dwarfs that will Merge within 500 Myr
Mukremin Kilic, Warren R. Brown, Carlos Allende Prieto +2
We present radial velocity observations of four extremely low-mass (0.2 Msol) white dwarfs. All four stars show peak-to-peak radial velocity variations of 540 - 710 km/s with 1.0 -…
New evolutionary sequences for hot H-deficient white dwarfs on the basis of a full account of progenitor evolution
L. G. Althaus, J. A. Panei, M. M. Miller Bertolami +5
We present full evolutionary calculations appropriate for the study of hot hydrogen-deficent DO white dwarfs, PG 1159 stars, and DB white dwarfs. White dwarf sequences are computed…
Evolution and colors of helium-core white dwarf stars with high-metallicity progenitors
L. G. Althaus, J. A. Panei, A. D. Romero +4
Motivated by the recent detection of single and binary He-core white dwarfs in metal-rich clusters, we present a full set of evolutionary calculations and colors appropriate for th…
