Relation between the parameters of dust and of molecular and atomic gas in extragalactic star-forming regions
Smirnova, K. I.; Wiebe, D. S.; Sobolev, A. M. +1 more
The relationships between atomic and molecular hydrogen and dust of various sizes in extragalactic star-forming regions are considered, based on observational data from the Spitzer and Herschel infrared space telescopes, the Very Large Array (atomic hydrogen emission) and IRAM (CO emission). The source sample consists of approximately 300 star-for…
Infrared Morphology of Regions of Ionized Hydrogen
Wiebe, D. S.; Kirsanova, M. S.; Topchieva, A. P. +1 more
A search for infrared ring nebulae associated with regions of ionized hydrogen has been carried out. The New GPS Very Large Array survey at 20 cm forms the basis of the search, together with observations obtained with the Spitzer Space Telescope at 8 and 24 µm and the Herschel Space Telescope at 70 µm. Objects having ring-like morpholo…
Search for close stellar encounters with the solar system from data on nearby dwarfs
Bobylev, V. V.
Trigonometric parallaxesmeasuredwith ground-based telescopes of the RECONS consortium as part of the CTIOPI program are used to search for stars that have either had an encounter with the solar system in the past or will have such an encounter in the future, at distances of less than a few parsecs. These are mainly low-mass dwarfs and subdwarfs of…
A dynamical study of the multiple system 17 Cygni ABFG
Romanenko, L. G.
Adynamical study of the relative motions of the components of the inner pairs AB (ADS 12913) and FG (ADS 12889) of the quadruple heirarchical system 17 Cygni (WDS 19464+3344) is presented, as well as analysis of themotions of the outer pair AB-FG. The study is based on CCD observations obtained on the 26-inch refractor of the Pulkovo Observatory (…
