Asteroseismic inference on rotation, gyrochronology and planetary system dynamics of 16 Cygni
García, R. A.; Chaplin, W. J.; Lund, M. N. +13 more
The solar analogues 16 Cyg A and B are excellent asteroseismic targets in the Kepler field of view and together with a red dwarf and a Jovian planet form an interesting system. For these more evolved Sun-like stars we cannot detect surface rotation with the current Kepler data but instead use the technique of asteroseimology to determine rotationa…
Direction of interstellar hydrogen flow in the heliosphere: theoretical modelling and comparison with SOHO/SWAN data
Katushkina, O. A.; Izmodenov, V. V.; Alexashov, D. B.
The analysis of SOlar and Heliospheric Observatory (SOHO) Solar Wind ANisotropies (SWAN) data for backscattered solar Lyman α radiation performed by Lallement et al. showed for the first time that the average direction of interstellar hydrogen flow in the heliosphere is deflected by several degrees relative to the original direction of the interst…
A method of complex background estimation in astronomical images
Popowicz, A.; Smolka, B.
In this paper, we present a novel approach to the estimation of strongly varying backgrounds in astronomical images by means of small-objects removal and subsequent missing pixels interpolation. The method is based on the analysis of a pixel local neighbourhood and utilizes the morphological distance transform. In contrast to popular background-es…
