B stars UBV and SpType catalogue
The present work represents a catalogue of spectral classification and photometric data of 2047 B type stars using the {Delta}Q method. Cone search capability for table... -
White dwarfs in LAMOST DR5
In this paper, we report white dwarfs (WD) identified in the 5th Data Release of the Large Area Multi-Object fibre Spectroscopic Telescope (LAMOST), including spectral types of... -
Neural networks for spectral classification
Due to the ever-expanding volume of observed spectroscopic data from surveys such as SDSS and LAMOST, it has become important to apply artificial intelligence (AI) techniques... -
Unclassified B[e] stars in the MW, SMC and LMC
We investigated 12 unclassified B[e] stars or candidates, 8 from the Galaxy, 2 from the Large Magellanic Cloud (LMC), and 2 from the Small Magellanic Cloud (SMC). Based on the... -
IR photometry of LMC long-period variables
Infrared JHK photometry and visual spectra have been obtained for a large sample of long-period variables (LPVs) in the Large Magellanic Cloud (LMC). Various aspects of the... -
Rosat North Ecliptic survey stellar population
X-ray surveys are a very efficient mean of detecting young stars and therefore allow us to study the young stellar population in the solar neighborhood and the local star... -
Revised spectral types of B-supergiants in the SMC
The problem of the classification of metal poor stars, such as occur in the Small Magellanic Cloud (SMC), is discussed with reference to the applicability of the MK system in... -
Galactic kinematics from YSOs sample
Based on published sources, we have created a kinematic database on 220 massive (>10M_{sun}) young Galactic star systems located within <3 kpcof the Sun. Out of them,... -
Observations of O and B stars
This catalog of O and B stars contains magnitudes, colors, spectral types and polarization for 1259 stars. In addition to observations, the catalogue contains the derived... -
Kinematic & fundamental parameters; OB stars
Runaway OB stars are ejected from their parent clusters via two mechanisms, both involving multiple stars: the dynamical ejection scenario (DES) and the binary supernova... -
Photometry of substellar candidates in ONC with JWST
In 2022, the James Webb Space Telescope (JWST) obtained 1-5um images of the center of the Orion Nebula Cluster (ONC). I have analyzed these data in an attempt to search for... -
Optical spectroscopy of {rho} Oph stars. II.
We have completed an optical spectroscopic survey of an unbiased, extinction-limited sample of candidate young stars covering 1.3deg^2^ of the {rho} Ophiuchi star-forming... -
8500-8750{AA} high resolution spectroscopy
We present an Echelle+CCD high resolution spectroscopic atlas mapping the MKK classification system over the wavelength interval lambda 8500-8750 A, centered on the near-IR... -
Spectral class. of dusty massive stars
Episodic mass-loss events such as giant eruptions in luminous blue variables or pre-supernova eruptions in red supergiants drastically alter the evolutionary path of a massive... -
APOGEE full information on classes
The volume of data generated by astronomical surveys is growing rapidly. Traditional analysis techniques in spectroscopy either demand intensive human interaction or are... -
Of-type stars in N206 in the LMC
Massive stars severely influence their environment by their strong ionizing radiation and by the momentum and kinetic energy input provided by their stellar winds and... -
New survey of supergiants in the MCs
In this study, we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end... -
AGB candidates in NGC 6822
The ratio of C- and M-type asymptotic giant branch (AGB) stars is commonly used to estimate the metallicity of extragalactic populations. Sources in the AGB population must... -
Velocities in SMC field of NGC 330
We search for the effects of metallicity on B and Be stars in the Small and Large Magellanic Clouds (SMC and LMC) and in the Milky Way (MW), by extending our previous analysis... -
Stars classified from S2/68 UV line features
This catalog provides the spectral classifications of 1900 stars from the papers listed in References. The classifications were made from spectra obtained by the S2/68 sky...
