We present time resolved spectroscopy of the newly discovered magnetic CV HS 0922+1333. Our observations show that it has a period of 244±2 min. Its optical spectra are dominated by a strong single spot cyclotron line at 5334Å. A detailed analysis shows that further cyclotron harmonics are at 7800Å (hidden by the M dwarf companion) and at 4034Å which yields a field strength of 66 MG (n = 2, 3 a...

The rotational spectral lines of methylformate (HCOOCH3) have been detected toward a low-mass protostar, NGC 1333 IRAS 4B, with the Nobeyama 45m radio telescope. The column density is derived to be (7–37)× 1015 cm−2, assuming a source size of 1′′ and the range of the excitation temperature to be from 50K to 200K. The column density is almost comparable to those found in other low-mass star-form...

Context. HCN, HNC, and their isotopologues are ubiquitous molecules that can serve as chemical thermometers evolutionary tracers to characterize star-forming regions. Despite importance in carrying information is vital studies of the chemistry evolution regions, collision rates some these have not been available for rigorous past. Aims. Our goal perform an up-to-date gas dust characterization t...

ABSTRACT We use photometric and kinematic data from Gaia DR2 to explore the structure of star-forming region associated with molecular cloud Perseus. Apart two well-known clusters, IC 348 NGC 1333, we present five new clustered groups young stars, which contain between 30 300 members, named Autochthe, Alcaeus, Heleus, Electryon, Mestor. demonstrate that these are co-moving based on how candidat...
