A method of immediate detection of objects with a near-zero apparent motion in series of CCD-frames
V. E. Savanevych, S. V. Khlamov, I. B. Vavilova +9
The paper deals with a computational method for detection of the solar system minor bodies (SSOs), whose inter-frame shifts in series of CCD-frames during the observation are comme…
KDG 218, a Nearby Ultra-Diffuse Galaxy
I. D. Karachentsev, L. N. Makarova, M. E. Sharina +1
We present properties of the low-surface-brightness galaxy KDG 218 observed with the HST/ACS. The galaxy has a half-light (effective) diameter of and a cen…
Spiral arms in CALIFA galaxies traced by non-circular velocities, abundances, and extinctions
F. Sakhibov, I. A. Zinchenko, L. S. Pilyugin +3
We derive maps of the observed velocity of ionized gas, the oxygen abundance, and the extinction (Balmer decrement) across the area of the four spiral galaxies NGC36, NGC180, NGC60…
Open star clusters in the Milky Way - Comparison of photometric and trigonometric distance scales based on Gaia TGAS data
Dana A. Kovaleva, Anatoly E. Piskunov, Nina V. Kharchenko +5
The global survey of star clusters in the Milky Way (MWSC) is a comprehensive list of 3061 objects that provides, among other parameters, distances to clusters based on isochrone f…
Breaks in surface brightness profiles and radial abundance gradients in the discs of spiral galaxies
L. S. Pilyugin, E. K Grebel, I. A. Zinchenko +2
We examine the relation between breaks in the surface brightness profiles and radial abundance gradients within the optical radius in the discs of 134 spiral galaxies from the CALI…
Comparison of Solar Fine Structure Observed Simultaneously in Ly-α and Mg II h
D. J. Schmit, A. V. Sukhorukov, B. De Pontieu +9
The Chromospheric Lyman Alpha Spectropolarimeter (CLASP) observed the Sun in H I Lyman-α during a suborbital rocket flight on September 3, 2015. The Interface Region Imaging Telesc…
