GMRT Survey of Radio Emission from Magnetic Massive Stars -- I: Emission from Single Stars at sub-GHz Frequencies
Ayan Biswas, Gregg A. Wade, Barnali Das +2
With the growing subset of magnetic massive stars, it is now possible to conduct a systematic survey of radio emission from magnetic hot stars to better understand the underlying e…

Discoveries of fine structures and secondary pulses in coherent radio emission from a magnetic massive star
Barnali Das, Poonam Chandra, William Cotton +1
In this paper, we report auroral radio emission from a magnetic B star HD 142990 using the MeerKAT radio telescope at MHz. The star is known to produce such emission (ob…

Coherent radio emission from 'Main-sequence Radio Pulse emitters': a new stellar diagnostic to probe 3D magnetospheric structures
Barnali Das, Poonam Chandra, Veronique Petit
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 b…
