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... -
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... -
GALAH observational overview
The Galactic Archaeology with HERMES (GALAH) Survey is a massive observational project to trace the Milky Way's history of star formation, chemical enrichment, stellar migration... -
Deep OB star population in Carina
Massive OB stars are critical to the ecology of galaxies, and yet our knowledge of OB stars in the Milky Way, fainter than V~12, remains patchy. Data from the VST Photometric... -
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... -
SCUBA-2 850um survey of the JWST-TDF & 3GHz VLA obs.
The James Webb Space Telescope Time-Domain Field (JWST-TDF) is an ~14' diameter field near the North Ecliptic Pole that will be targeted by one of the JWST Guaranteed Time... -
COS Legacy Archive Sp. Survey (CLASSY) treasury
Far-ultraviolet (FUV; ~1200-2000{AA}) spectra are fundamental to our understanding of star-forming galaxies, providing a unique window on massive stellar populations, chemical... -
HST/COS obs. of QSO outflows in 500-1050{AA}. VII.
From Hubble Space Telescope/Cosmic Origins Spectrograph spectra of five quasars, 16 outflows are detected. For 11 outflows, we are able to constrain their distances to the... -
K2 star parameters from Gaia & LAMOST
Previous measurements of stellar properties for K2 stars in the Ecliptic Plane Input Catalog (EPIC) largely relied on photometry and proper motion measurements, with some added...
