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... -
An all-sky catalogue of stellar reddening values
When observing astronomical objects, we have to deal with extinction (i.e. the absorption and scattering of the emitted radiation by dust and gas between the source and the... -
Membership for open clusters with Gaia DR2
Open clusters are groups of stars that form at the same time, making them an ideal laboratory to test theories of star formation, stellar evolution, and dynamics in the Milky... -
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... -
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... -
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... -
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... -
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,... -
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... -
Maps of dust distribution in M31 bulge
We map the dust distribution in the central 180" (~680pc) region of the M31 bulge, based on HST WFC3 and ACS observations in ten bands from near-ultraviolet (2700{AA}) to... -
A deep catalogue of classical Be stars
We present a catalogue of 247 photometrically and spectroscopically confirmed fainter classical Be stars (13<r<16) in the direction of the Perseus Arm of the Milky Way... -
Simulated UVEX colors with reddening
The UV-Excess survey of the northern Galactic plane images a 10{deg}x185{deg} wide band, centred on the Galactic equator using the 2.5-m Isaac Newton Telescope in four bands (U,... -
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,... -
Extension of HOPS out to 500pc (eHOPS). I. Aquila
We present a Spitzer/Herschel focused survey of the Aquila molecular clouds (d~436pc) as part of the eHOPS (extension of the Herschel orion protostar survey, or HOPS, Out to 500... -
Opt. spectra of blue MIR objects in LMC
We present low-resolution optical spectra and classifications of 92 blue objects with mid-infrared excesses in the Large Magellanic Cloud. The majority of these objects were...
