CCD Photometry of the Open Cluster Tombaugh 5 in the Vilnius System

Open Astronomy, 2011
We present the results of eight-color CCD photometry of 674 stars in the direction of the open cluster Tombaugh 5 in Camelopardalis. The stars are observed in the Vilnius system supplemented by the broad-band I filter; the field is of 22’ diameter, the ...

UV radiation fields in dark clouds

How dark is it inside a dark cloud? If—as is currently believed-interstellar extinction at UV wavelengths is mainly due to scattering with a strongly forward throwing phase-function, the interior of a dark cloud may be much better illuminated at UV ...

The Molecular Inventory of TMC-1 with GOTHAM Observations

The Astrophysical Journal Supplement Series
Spectral line surveys of the Taurus Molecular Cloud-1 (TMC-1) have led to the detection of more than 100 new molecular species, making it the most prolific source of interstellar molecular discoveries.

Magnetomechanical supersonic waves in dark molecular clouds

, 2017
We propose and investigate the magnetoelastodynamic mechanism of the wave motions of poorly ionized superparamagnetic gas-dust interstellar medium capable of sustaining long-ranged magnetization.

Photocleavage of Aliphatic C–C Bonds in the Interstellar Medium

The Astrophysical Journal
Ultraviolet (UV) processing in the interstellar medium (ISM) induces the dehydrogenation of hydrocarbons. Aliphatics, including alkanes, are present in different interstellar environments, being prevalently formed in evolved stars; thus, the ...

PHOSPHORUS CHEMISTRY IN DENSE INTERSTELLAR CLOUDS

, 1991
I have used recent laboratory studies on the reactions of the phosphorus hydride ions, PH(n)+ (n = 0-4) to construct a new model of phosphorus chemistry in interstellar clouds.
