Properties of radio-loud BAL quasars
We recently presented radio observations of a large sample of radio-loud broad absorption line (BAL) quasars from the Sloan Digital Sky Survey (SDSS) and Faint Images of the... -
H{alpha} variations of O9 subgiant HD57682
The O9IV star HD 57682, discovered to be magnetic within the context of the Magnetism in Massive Stars (MiMeS) survey in 2009, is one of only eight convincingly detected... -
CaII equivalent widths of dM1 stars
We present 187 high-resolution spectra for 62 different M1 dwarfs from observations obtained with the FIbre-fed Echelle Spectrograph (FIES) on the Nordic Optical Telescope (NOT)... -
Berkeley supernova Ia program. II.
In this second paper in a series, we present measurements of spectral features of 432 low-redshift (z<0.1) optical spectra of 261 Type Ia supernovae (SNe Ia) within 20d of... -
Low-mass stars spectroscopy in NGC 2516
We present far-red, intermediate-resolution spectroscopy of 572 photometrically selected, low-mass stars (0.2<M/M_{sun}_<0.7) in the young open cluster NGC 2516, using the... -
Equivalent widths of 11 NGC 3680 stars
We present a new abundance analysis of the intermediate-age Galactic open cluster NGC 3680, based on high-resolution, high signal-to-noise ratio VLT/UVES spectroscopic data.... -
Candidate Be stars in the Magellanic Clouds
Mennickent et al. (2002A&A...393..887M) and Sabogal et al. (2005, Cat. J/MNRAS/361/1055) identified a large number of classical Be (CBe) candidates (~3500) in the Large and... -
2 new candidate luminous blue variables
We report the discovery of two new Galactic candidate luminous blue variable (LBV) stars via detection of circular shells (typical of confirmed and candidate LBVs) and follow-up... -
CaII and H{alpha} data for dK5/dM4 stars
We use 665 high-resolution spectra for 60 different dM4 stars and 1088 high-resolution spectra for 97 different dK5 stars from the European Southern Observatory (ESO) and... -
Red giants abundances in 4 open clusters
We have analysed high-dispersion echelle spectra (R>~50000) of red giant members for four open clusters to derive abundances for many elements. The spread in temperatures and... -
NLTE corrections for Mg and Ca lines
We investigate NLTE effects for magnesium and calcium in the atmospheres of late-type giant and supergiant stars. The aim of this paper is to provide a grid of NLTE/LTE... -
H{alpha} emitters at z=2.23
We present the results of a narrow-band (H_2_S1, {lambda}c=2.121um, {delta}{lambda}=0.021um) imaging search with Wide Field Camera/United Kingdom Infrared Telescope for H{alpha}... -
VLT Lyman-break galaxy redshift survey. II.
We have measured redshifts for 243 z~~3 quasars in nine Very Large Telescope (VLT) Visible Imaging and Multi-Object Spectrograph (VIMOS) Lyman-break galaxy (LBG) redshift survey... -
Spectroscopy of of IC4499 red giants
We present radial velocity and metallicity measurements for the far southern Galactic globular cluster IC 4499. We selected several hundred target red giant stars in and around... -
CaII triplet in Sextans dSph galaxy
We use Very Large Telescope (VLT)/Fibre Large Array Multi Element Spectrograph (FLAMES) intermediate-resolution (R~6500) spectra of individual red giant branch stars in the... -
Supernova Legacy Survey. Type Ia supernovae
Optical long-slit spectroscopy at the Gemini-North telescope using the Gemini Multi-Object Spectrograph (GMOS) was used to classify targets from the Supernova Legacy Survey... -
Helium-rich subluminous B stars abundances
The connection between helium-rich hot subdwarfs of spectral types O and B (He-sdB) has been relatively unexplored since the latter were found in significant numbers in the... -
Fast-rotating M dwarfs in NGC2516
We report radial velocities (RVs), projected equatorial velocities (vsini) and CaII triplet (CaT) chromospheric activity indices for 237 late-K to mid-M candidate members of the... -
Heavy element abundances in HD 209621
High-resolution spectra obtained from the Subaru Telescope High Dispersion Spectrograph have been used to update the stellar atmospheric parameters and metallicity of the star... -
Dwarf galaxies in Coma supercluster
We analyse Spitzer Multiband Imaging Photometer (MIPS) 24um observations, and Sloan Digital Sky Survey Data Release 7 optical broad-band photometry and spectra, to investigate...
