Pseudomagnitude distances applied to the Pleiades
The concept of pseudomagnitude was recently introduced to estimate apparent stellar diameters using a strictly observational methodology. Pseudomagnitudes are distance... -
IPHAS-selected classical Be stars
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD)... -
Pulsation model data for delta Cep and eta Aql
The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface brightness technique, is an elegant method to determine distances... -
Deep SDSS Optical Spectroscopy. II.
We analyze a sample of 3942 low-resolution (R~2000) optical spectra from the Sloan Digital Sky Survey (SDSS), focusing on stars with effective temperatures 5800 -
GSH 305+01-24 stellar content
The distribution of OB stars along with that of H{alpha}, ^12^CO, dust infrared emission, and neutral hydrogen is carried out in order to provide a more complete picture of... -
uvby{beta} photometry in Carina. II
In recent years a significant development has become evident in the study of the stellar structure of the Galactic disk. This is especially true for the 3rd Galactic quadrant,... -
Distances of nearby ultracool dwarfs
We present updated results of spectroscopic follow-up observations of a sample of 45 M dwarf candidates identified by Phan-Bao et al. (2003, Cat. ) based on the DENIS photometry... -
Spectroscopic distances of 322 NLTT stars
Distance estimates based on low-resolution spectroscopy and Two Micron All Sky Survey (2MASS, Cat. ) J magnitudes are presented for 322 nearby candidates from Luyten's NLTT... -
Bp-Ap stars HR-diagram from Hipparcos data
Using Hipparcos (Cat. ) parallaxes and proper motions together with radial velocity data, the luminosity calibration and kinematics of Bp-Ap stars have been obtained. The used... -
Mass segregation in open clusters
On the basis of the best available member list and duplicity information, we have studied the radial structure of Praesepe and of the very young open cluster NGC 6231. We have... -
Metal-poor stars spectroscopy. II
Models of post-main sequence stellar evolution of VandenBerg & Bell have been applied to determine spectroscopic masses and distances for metal-poor stars. Careful... -
Cartesian catalog of 30 million Gaia sources
Accurate measurements of stellar positions and velocities are crucial for studying galactic and stellar dynamics. We aim to create a Cartesian catalog from Gaia DR3 to serve as... -
StarHorse2, Gaia EDR3 photo-astrometric distances
We present a catalogue of 362 million stellar parameters, distances, and extinctions derived from Gaia's Early Data Release (EDR3) cross-matched with the photometric catalogues... -
Distances to 1.47 billion stars in Gaia EDR3
Stellar distances constitute a foundational pillar of astrophysics. The publication of 1.47 billion stellar parallaxes from Gaia is a major contribution to this. Yet despite... -
StarHorse, Gaia DR2 photo-astrometric distances
Combining the precise parallaxes and optical photometry delivered by Gaia's second data release with the photometric catalogues of Pan-STARRS1, 2MASS, and AllWISE, we derived... -
Distances to 1.33 billion stars in Gaia DR2
For the majority of stars in the second Gaia data release, reliable distances cannot be obtained by inverting the parallax. A correct inference procedure must instead be used to... -
A comprehensive analysis of Spitzer supernovae
The mid-infrared (mid-IR) wavelength regime offers several advantages for following the late-time evolution of supernovae (SNe). First, the peaks of the SN spectral energy... -
Simulated exoplanets from TESS list of targets
The Transiting Exoplanet Survey Satellite (TESS) has a goal of detecting small planets orbiting stars bright enough for mass determination via ground-based radial velocity...
