Planetary Nebulae with Ultra-Violet Imaging Telescope (UVIT): Far Ultra-violet halo around the Bow Tie nebula (NGC 40)
N. Kameswara Rao, F. Sutaria, J. Murthy +3
Context. NGC 40 is a planetary nebula with diffuse X-ray emission, suggesting an interaction of the high speed wind from WC8 central star (CS) with the nebula. It shows strong Civ…
Modelling type IIP/IIL supernovae interacting with recent episodic mass ejections from their presupernova stars with MESA & SNEC
Sanskriti Das, Alak Ray
We show how dense compact discrete shells of circumstellar gas immediately outside the red supergiants affect the optical light curves of type II-P/II-L SNe taking the example of S…
Rigorous Quantum Limits on Monitoring Free Masses and Harmonic Oscillators
S. M. Roy
There are heuristic arguments proposing that the accuracy of monitoring position of a free mass is limited by the standard quantum limit (SQL):$σ^2 (X(t)) \geq σ^2 (X(0)) +(t^2…
Gravitomagnetism and Pulsar Beam Precession near a Kerr Black Hole
Prashant Kocherlakota, Pankaj S. Joshi, Sudip Bhattacharyya +3
A rotating black hole causes the spin-axis of a nearby pulsar to precess due to geodetic and gravitomagnetic frame-dragging effects. The aim of our theoretical work here is to expl…
A Lower Bound on Inelasticity in Pion-Pion Scattering
André Martin, S. M. Roy
Assuming that the pion-pion scattering amplitude and its absorptive part are analytic inside an ellipse in - plane with foci , and right extremity , ($ε…
Seismic measurement of the locations of the base of convection zone and helium ionization zone for stars in the {\it Kepler} seismic LEGACY sample
Kuldeep Verma, Keyuri Raodeo, H. M. Antia +4
Acoustic glitches are regions inside a star where the sound speed or its derivatives change abruptly. These leave a small characteristic oscillatory signature in the stellar oscill…
