CCD polarimetry of distant comets C/2010 S1 (LINEAR) and C/2010 R1 (LINEAR) at the 6-m telescope of the SAO RAS
Oleksandra V. Ivanova, Janna M. Dlugach, Viktor L. Afanasiev +2
We present first measurements of the degree of linear polarization of distant comets C/2010 S1 (LINEAR) and C/2010 R1 (LINEAR) at heliocentric distances r= 5.9 - 7.0 AU. Observatio…
DE082349 is a juvenile binary brown dwarf at 20.7 pc
J. Sahlmann, A. J. Burgasser, E. L. Martín +6
Astrometric monitoring of the nearby early-L dwarf DE082349 has revealed a low-mass companion in a 248-day orbit that was announced in an earlier work. Here, we present new astr…
A search for lithium in metal-poor L dwarfs
N. Lodieu, A. J. Burgasser, Y. Pavlenko +1
The aim of the project is to search for lithium in absorption at 6707.8 Angstroms to constrain the nature and the mass of the brightest low-metallicity L-type dwarfs (refered to as…
Abundances in the atmosphere of the metal-rich planet-host star HD 77338
I. O. Kushniruk, Ya. V. Pavlenko, J. S. Jenkins +1
Abundances of Fe, Si, Ni, Ti, Na, Mg, Cu, Zn, Mn, Cr and Ca in the atmosphere of the K-dwarf HD 77338 are determined and discussed. HD 77338 hosts a hot Uranus-like planet and is c…
A new method based on the subpixel Gaussian model for accurate estimation of asteroid coordinates
V. E. Savanevych, O. B. Briukhovetskyi, N. S. Sokovikova +8
We describe a new iteration method to estimate asteroid coordinates, which is based on the subpixel Gaussian model of a discrete object image. The method operates by continuous par…
New candidates for extremely metal-poor emission-line galaxies in the SDSS/BOSS DR10
N. G. Guseva, Y. I. Izotov, K. J. Fricke +1
We present a spectroscopic study of eight extremely low-metallicity candidate emission-line galaxies with oxygen abundances possibly below 12 +log O/H = 7.35. These galaxies were s…
