Southern reddened luminous stars. II.
H{beta} photometry is given for 263 reddened and very reddened stars from the Stephenson & Sanduleak (1971, Cat. ) catalogue of Luminous Stars in the Southern Milky Way... -
E(V-I) reddening map of MCs from OGLE-IV RC stars
We present the most extensive and detailed reddening maps of the Magellanic Clouds (MCs) derived from the color properties of Red Clump (RC) stars. The analysis is based on the... -
Metal-poor stars in the thick disk of the Galaxy
A new set of very high signal-to-noise (S/N>100/1), medium-resolution (R~3000) optical spectra have been obtained for 302 of the candidate "weak-metal" stars selected by... -
Pan-STARRS1 transients optical photometry
In the past decade, several rapidly evolving transients have been discovered whose timescales and luminosities are not easily explained by traditional supernovae (SNe) models.... -
JHKL photometry of the Galactic Center
J, H, K, and L photometry for the stars in the central ~2' (~5pc) of the Galaxy are presented. Using the observed J-H, H-K, and K-L colors and assumed intrinsic colors, we... -
Globular and open clusters observed by SDSS/SEGUE
We present griz observations for the clusters M92, M13 and NGC 6791 and gr photometry for M71, Be 29 and NGC 7789. In addition we present new membership identifications for all... -
UBVRIz light curves of 51 Type II supernovae
We present a compilation of UBVRIz light curves of 51 type II supernovae discovered during the course of four different surveys during 1986-2003: the Cerro Tololo Supernova... -
3D map of reddening and interstellar extinction
An improved version of the 3D stellar reddening map in a space with a radius of 1200 pc around the Sun and within 600 pc of the Galactic midplane is presented. As in the... -
Total-to-selective extinction ratio within 700pc
Multicolor photometry from the Tycho-2 and 2MASS catalogues for 11990 OB (2008AstL...34....7G; 2012AstL...38..694G) and 30671 K-type red giant branch stars (2011AstL...37..707G)... -
3D interstellar extinct. map within nearest kpc
The product of the previously constructed 3D maps of stellar reddening (Gontcharov, 2010AstL...36..584G, Cat. J/PAZh/36/615) and Rv variations (Gontcharov, 2012AstL...38...12G,... -
3D reddening map for stars from 2MASS phot.
A three-dimensional reddening map for stars within 1100pc of the Sun are presented. Analysis of the distribution of 70 million stars from the 2MASS catalog with the most... -
Galactic reddening maps
Accurate maps of Galactic reddening are important for a number of applications, such as mapping the peculiar velocity field in the nearby universe. Of particular concern are... -
New Wide Common Proper Motion Binaries
In this work we report the discovery of 150 new double stars of which 142 are wide common proper motion stellar systems. In addition to this, we report the study of 23 recently... -
NIR light curves study of DCEPs in the LMC
We employed the VISTA near-infrared YJKs survey of the Magellanic System (VMC) to analyse the Y, J, K_s_ light curves of {delta} Cepheid stars (DCEPs) in the Large Magellanic... -
Short-period binaries in the inner VVV bulge
Most of our knowledge of the structure of the Milky Way has come from the study of variable stars. Among these variables, mimicking the periodic variation of pulsating stars,... -
Reddening of SMC red clump stars
Galaxy interactions distort the distribution of baryonic matter and can affect star formation. The nearby Magellanic Clouds are a prime example of an ongoing galaxy interaction... -
Small Magellanic Cloud's background galaxies
We present a map of the total intrinsic reddening across ~34deg^2^ of the Small Magellanic Cloud (SMC) derived using optical (ugriz) and near-infrared (IR; YJK_s_) spectral... -
{lambda} Bootis stars: the Southern Survey II.
The {lambda} Boo stars are chemically peculiar A-type stars whose abundance anomalies are associated with the accretion of metal-poor material. We searched for {lambda} Boo... -
Updated PA and PAC relations for Cepheids
Updated evolutionary and pulsational model predictions are combined in order to interpret the properties of Galactic Classical Cepheids in the Gaia Data Release 2. In... -
Faint LSB galaxy cand. in Perseus cluster
We present the detection of 89 low surface brightness (LSB), and thus low stellar density galaxy candidates in the Perseus cluster core, of the kind named 'ultra-diffuse...
