Star formation in isolated galaxies
We use the FUV fluxes measured with the GALEX to study the star formation properties of galaxies collected in the Local Orphan Galaxies catalog (LOG, 2011AstBu..66....1K). Among... -
Nearby multiple Speckle interferometry. V.
The results of speckle interferometric observations of 194 binary stars performed at the BTA 6m telescope in 2002-2006 are presented in this paper. For speckle observations we... -
Galaxies in Lynx-Cancer void
In this work we present the results of photometrical study of 85 objects from the updated sample of galaxies residing in the nearby Lynx-Cancer void. The images in filters... -
Southern reddened luminous stars. III.
V(RI)C photometry has been obtained for 262 reddened and very reddened stars selected from the Stephenson & Sanduleak (1971, Cat. ) catalogue of Luminous Stars in the... -
Speckle interferometry of Ap stars. II.
We present the results of speckle interferometric observations of 156 stars possessing global magnetic fields, carried out with the 6-m BTA telescope of the Special... -
UBVRI photometry of GSPC stars
Photoelectric UBVRI observations are given for 336 stars brighter than 11.5mag from the Hubble Space Telescope Guide Star Photometric Catalogue (GSPC). Apart from a... -
Southern reddened luminous stars. I.
Stroemgren uvby photometry has been obtained for 270 reddened and very reddened OB stars selected from the Stephenson & Sanduleak (1971) catalogue of Luminous Stars in the... -
Standard errors for PPM and Tycho stars
The connection between the optical reference frame and the radio one constitutes one of the main purposes of the astrometry. The paper is pointing out the contribution of the... -
DDO photometry of E-region stars
This paper describes the observations and gives the results of a series of observations of bright E-region stars (Cousins A.W.J. and Stoy R.H., 1962RGOB...49....3C) for use as... -
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... -
Southern reddened luminous stars. IV.
Infrared JHK measurements are presented for 232 reddened and very reddened stars selected from the Stephenson & Sanduleak (1971, Cat. ) catalogue of Luminous Stars in the... -
UBV photometry of HD stars
Photoelectric UBV photometry is presented for over 400 HD stars which lie within about a degree of selected cataclysmic variables. The data will be combined with polarimetry to... -
Candidate halo dark matter
The Milky Way galaxy contains a large, spherical component which is believed to harbor a substantial amount of unseen matter. Recent observations indirectly suggest that as much... -
Relativistic jets from black hole systems
Black holes generate collimated, relativistic jets, which have been observed in {gamma}-ray bursts (GRBs), microquasars, and at the center of some galaxies [active galactic... -
Kepler-47 transits
We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times... -
RV curves of Galactic massive O stars
The presence of a nearby companion alters the evolution of massive stars in binary systems, leading to phenomena such as stellar mergers, X-ray binaries and gamma-ray bursts.... -
1.3mm VLBI detections of M87
Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by the accretion of matter onto supermassive black holes. Although the measured width... -
Pseudo-3D maps of DIB at 862nm
The diffuse interstellar bands (DIBs) are absorption lines observed in visual and near-infrared spectra of stars. Understanding their origin in the interstellar medium is one of... -
Sgr A East SNR multiwavelength images
Dust formation in supernova ejecta is currently the leading candidate to explain the large quantities of dust observed in the distant, early universe. However, it is unclear... -
51 Eri b near-infrared spectrum
Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric composition and luminosity, which is influenced by their formation...
