Lunar Eclipse of June, 15, 2011: Three-color umbra surface photometry
Lunar Eclipse Three-color umbra
2011/9/29
The paper contains the preliminary result description of the photometric observations of the Moon surface during the total lunar eclipse of June, 15, 2011 conducted in southern Russia and Ukraine in t...
Faint NUV/FUV Standards from Swift/UVOT, GALEX and SDSS Photometry
Faint NUV/FUV Standards Swift/UVOT GALEX SDSS Photometry
2011/1/11
At present, the precision of deep ultraviolet photometry is somewhat limited by the dearth of faint ultraviolet standard stars. In an effort to improve this situation, we present a uniform catalog of ...
Warm Spitzer Photometry of the Transiting Exoplanets CoRoT-1 and CoRoT-2 at Secondary Eclipse
stars planetary systems eclipses techniques photometric
2010/11/10
We measure secondary eclipses of the hot giant exoplanets CoRoT-1 at 3.6 and 4.5 μm, and CoRoT-2 at 3.6 μm, both using Warm Spitzer. We find that the Warm Spitzer mission is working very well for exop...
Dwarf galaxies in the nearby Lynx-Cancer void: photometry, colours and ages
Dwarf galaxies photometry colours ages
2010/11/16
The nearby Lynx-Cancer void is a good laboratory to study the effect of very rarefied environment on the evolution of the least massive dwarf galaxies. A recently compiled sample of this void’s galaxi...
New limb-darkening coefficients and synthetic photometry for model-atmosphere grids at Galactic, LMC, and SMC abundances
New limb-darkening coefficients synthetic photometry for model-atmosphere grids SMC abundances
2010/11/15
New grids of Atlas9 models have been calculated using revised convection parame-ters and updated opacity-distribution functions, for chemical compositions intended to be representative of solar, [M/H]...
BVRI photometry of 53 unusual asteroids
Techniques photometric – Minor planets asteroids general
2010/11/9
We present the results of BV RI photometry and classification of 53 un-usual asteroids, including 35 near-Earth asteroids (NEAs), 6 high eccentric-ity/inclination asteroids, and 12 recently-identified...
A method to determine distances to molecular clouds using near-IR photometry
ISM dust extinction – ISM clouds – Stars distances – ISM individual objects L1517 –ISM Chamaeleon I –ISM
2010/11/15
Aims. To develop a method to determine distances to molecular clouds using JHK near-infrared photometry.Methods. The method is based on a technique that aids spectral classification of stars lying tow...
Optical and infrared photometry of the blazar PKS0537-441

2010/11/11
We present a large collection of photometric data on the Blazar PKS 0537-441 in the VRIJHK
bands taken in 2004−2009. At least three flare-like episodes with months duration, and >3 mag

2010/11/12
Context. Parallel analysis of the large-scale morphology and local environment of matched active and control galaxy samples plays an important role in studies of the fueling of active galactic nuclei.
Improving the Estimation of Star formation Rates and Stellar Population Ages of High-redshift Galaxies from Broadband Photometry
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We explore methods to improve the estimates of star formation rates and mean stellar population ages from broadband photometry of high redshift star-forming galaxies. We use synthetic spectral templat...
Detection of solar-like oscillations from Kepler photometry of the open cluster NGC 6819

2010/3/8
Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance and initial chemical composition allows strong tests of the theory of stellar evoluti...
