First monitoring campaign of a Main-sequence Radio Pulse emitter: the case of CU Vir
Barnali Das, Hayley Bignall, Andrew Zic +6
CU Vir, a magnetic hot star, is the first discovered Main-sequence Radio Pulse emitter (MRP) characterized by its ability to produce periodic radio pulses via electron cyclotron ma…
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…
XMM-Newton Perspective of the Unique Magnetic Binary- Lupi
Ayan Biswas, Gregg A. Wade, Poonam Chandra +3
The Lupi A (HD 136504) system stands out among magnetic massive binaries as the only short-period binary system in which both components have detectable magnetic fields. The pr…
Peculiar spectral property of coherent radio emission from a hot magnetic star: the case of an extreme oblique rotator
Barnali Das, Poonam Chandra
We report ultra-wideband (0.4-4.0 GHz) observation of coherent radio emission via electron cyclotron maser emission (ECME) produced by the hot magnetic star HD 142990. With nearly…
The accelerating rotation of the magnetic He-weak star HD 142990
M. Shultz, Th. Rivinius, B. Das +2
HD 142990 (V 913 Sco; B5 V) is a He-weak star with a strong surface magnetic field and a short rotation period ( d). While it is clearly a rapid rotator, recent…
