Coherent Radio Emission from “Main-sequence Radio Pulse Emitters”: A New Stellar Diagnostic to Probe 3D Magnetospheric Structures

The Astrophysical Journal
Main-sequence radio pulse emitters (MRPs) are magnetic early-type stars that produce coherent radio emission observed in the form of periodic radio pulses. The emission mechanism behind this is the electron-cyclotron maser emission (ECME).

Dynamics of OH masers in regions of star formation I

, 1999
A mathematical model for the explanation of OH masers in regions of star formation is presented. The model is based on the assumption that grains of different sizes are present at the border of the HII regions where they are exposed to the heat- and ...

Maser radiation from astrophysical jets

, 2016
Electromagnetic radiation from jets is normally considered to be incoherent synchrotron emission. Some aspects of radiation from both stellar and extragalactic jets could, however, be due to coherent emission mechanisms. Coherent radiation mechanisms have the advantage of being able to account for the high brightness temperatures inferred from some ...

Simultaneous VLBI Astrometry of H2O and SiO Masers toward the Semiregular Variable R Crateris

, 2018
We obtained, for the first time, astrometrically registered maps of the 22.2 GHz H2O and 42.8, 43.1, and 86.2 GHz SiO maser emission toward the semiregular b-type variable (SRb) R Crateris, at three epochs (2015 May 21, and 2016 January 7 and 26) using ...
