What leads to premature upper cut-off frequencies of auroral radio emission from hot magnetic stars?
B. Das, P. Chandra, V. Petit
Recently a large number of hot magnetic stars have been discovered to produce auroral radio emission by the process of electron cyclotron maser emission (ECME). Such stars have bee…
The effect of collisional cooling of energetic electrons on radio emission from the centrifugal magnetospheres of magnetic hot stars
B. Das, S. P. Owocki
This paper extends our previous study of gyro-emission by energetic electrons in the magnetospheres of rapidly rotating, magnetic massive stars, through a quantitative analysis of…
Non-linear Thermoelastic Analysis of an Anisotropic Rectangular Plate
B. Das, S. Chakraborty, A. Lahiri
Three-dimensional thermoelastic analysis in presence of electro magnetic field is investigated of a rectangular plate. In the context of Green-Naghdi model-II, fractional order ene…
A scaling relationship for non-thermal radio emission from ordered magnetospheres - II. Investigating the efficiency of relativistic electron production in magnetospheres of BA-type stars
P. Leto, S. Owocki, C. Trigilio +19
Magnetic BA stars host dipole-like magnetospheres. When detected as radio sources, their luminosities correlate with the magnetic field and rotation. Rotation is crucial because th…
MOBSTER -- VI. The crucial influence of rotation on the radio magnetospheres of hot stars
M. E. Shultz, S. P. Owocki, A. ud-Doula +13
Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons were previously thought to be accelerated to relativistic velocities in the current sheet f…
Flux Pinning by Nano Particles Embedded in Polycrystalline Y-123 Superconductors
Sushant Gupta, R. S. Yadav, B. Das
Bulk superconductor samples of YBa2Cu3-xZnxO7-δ with x = 0, 0.01, 0.03 are synthesized by solid-state reaction route. The structural characterisation of all samples has been carri…
