Blue supergiants low-frequency gravity waves
Almost all massive stars explode as supernovae and form a black hole or neutron star. The remnant mass and the impact of the chemical yield on subsequent star formation and... -
Red supergiant stars in binary systems. I. SMC
We aim to identify and characterise binary systems containing red supergiant (RSG) stars in the Small Magellanic Cloud (SMC) using a newly available ultraviolet (UV) point... -
Period-luminosity relation of red supergiants
We revisit the K-band period-luminosity (P-L) relations of Galactic red supergiants using Gaia Data Release 2 parallaxes and up to 70yr of photometry from AAVSO and ASAS... -
Red supergiant population in Perseus arm
We present a new catalogue of cool supergiants in a section of the Perseus arm, most of which had not been previously identified. To generate it, we have used a set of... -
IR photometry of LMC O-rich evolved stars
In order to determine the composition of the dust in the circumstellar envelopes of oxygen-rich asymptotic giant branch (AGB) stars, we have computed a grid of MODUST... -
Galactic and MC O-AGBs and RSGs stars
We investigate the occurrence of crystalline silicates in oxygen-rich evolved stars across a range of metallicities and mass-loss rates. It has been suggested that the... -
Chromospheric Mg II h+k flux of evolved stars
Of a total of 177 cool G, K and M giants and supergiants, we measured the MgII h+k line emission of extended chromospheres in high-resolution (LWR) International Ultraviolet... -
Reddenings of FGK supergiants & Cepheids
Accurate and homogeneous atmospheric parameters (Teff, logg, Vt, [Fe/H]) are derived for 74 FGK non-variable supergiants from high-resolution, high signal-to-noise ratio,... -
Energy distributions in giants and supergiants
Normal spectral energy distributions for early-type subgiants, giants and supergiants are derived. Cone search capability for table J/AZh/77/619/table1 (Giants used to derive... -
Granulations of red supergiants from ASAS-SN & iPTF
The mechanisms and characteristics of the irregular variations of red supergiants (RSGs) are studied based on the RSG samples in the Small Magellanic Cloud (SMC), Large... -
Red supergiant stars in the SMC. II.
The characteristics of light variation of red supergiant (RSG) stars in the Small Magellanic Cloud (SMC) are analyzed based on the nearly 8-10 year data collected by the ASAS... -
Red supergiant stars in the LMC. I.
From previous samples of red supergiants (RSGs) by various groups, 191 objects are assembled to compose a large sample of RSG candidates in LMC. For 189 of them, the identity as... -
O, B-type & red supergiant masses and luminosities
Massive stars are of interest as progenitors of supernovae, i.e. neutron stars and black holes, which can be sources of gravitational waves. Recent population synthesis models... -
Multiwavelength photometry of RCB stars
The study of extended, cold dust envelopes surrounding R Coronae Borealis (RCB) stars began with their discovery by the Infrared Astronomical Satellite. RCB stars are... -
VLT/SINFONI observations of MIPSGAL "bubbles"
We present Very Large Telescope/Spectrograph for INtegral Field Observations in the Near Infrared H- and K-band spectra of potential central stars within the inner 8"-by-8"... -
Stellar Models from 0.8 to 120 Msolar
New grids of stellar evolutionary models covering the range of 0.8 to 120 solar masses have been computed for metallicites Z=0.020 and Z=0.001. The models use the new opacities... -
LMC A-F supergiants
A survey for A-F type supergiants in the Large Magellanic Cloud has been carried out using UV objective prism plates. 890 objects were detected and their spectral types,... -
Using H-bump to identify RSGs in NGC6822
We present a case study in which we used a novel method to identify red supergiant (RSG) candidates in NGC 6822 based on their 1.6um H-bump. We collected 32 bands of photometric... -
A source catalog for the LMC
We present a clean, magnitude-limited (IRAC1 or WISE1<=15.0mag) multiwavelength source catalog for the Large Magellanic Cloud (LMC). The catalog was built by crossmatching... -
RSGs in the SMC
We present the most comprehensive red supergiant (RSG) sample for the Small Magellanic Cloud (SMC) to date, including 1239 RSG candidates. The initial sample was derived based...
