Multi-wavelength observations of multiple eruptions of the recurrent nova M31N 2008-12a
Judhajeet Basu, M. Pavana, G. C. Anupama +8
We report the optical, UV, and soft X-ray observations of the eruptions of the recurrent nova M31N 2008-12a. We infer a steady decrease in the accretion rate over the y…
The intermediate polar cataclysmic variable GK Persei 120 years after the nova explosion: a first dynamical mass study
A. Álvarez-Hernández, M. A. P. Torres, P. Rodríguez-Gil +15
We present a complete dynamical study of the intermediate polar and dwarf nova cataclysmic variable GK Per (Nova Persei 1901) based on a multi-site optical spectroscopy and -ban…
AstroSat Soft X-ray observations of the symbiotic recurrent nova V3890 Sgr during its 2019 outburst
K. P. Singh, V. Girish, M. Pavana +3
Two long AstroSat Soft X-ray Telescope observations were taken of the third recorded outburst of the Symbiotic Recurrent Nova, V3890 Sgr. The first observing run, 8.1-9.9 days afte…
Kilonova Luminosity Function Constraints based on Zwicky Transient Facility Searches for 13 Neutron Star Mergers
Mansi M. Kasliwal, Shreya Anand, Tomas Ahumada +100
We present a systematic search for optical counterparts to 13 gravitational wave (GW) triggers involving at least one neutron star during LIGO/Virgo's third observing run. We searc…
Spectroscopic and geometrical evolution of the ejecta of the classical nova ASASSN-18fv
M. Pavana, A. Raj, T. Bohlsen +3
The optical spectroscopic observations of ASASSN-18fv observed from 2018 March 24 to 2019 Jan 26 are presented. The optical spectra are obtained from Mirranook, Vainu Bappu and Sou…
GROWTH on S190425z: Searching thousands of square degrees to identify an optical or infrared counterpart to a binary neutron star merger with the Zwicky Transient Facility and Palomar Gattini IR
Michael W. Coughlin, Tomás Ahumada, Shreya Anand +76
The third observing run by LVC has brought the discovery of many compact binary coalescences. Following the detection of the first binary neutron star merger in this run (LIGO/Virg…
Optical spectroscopic and polarization properties of 2011 outburst of the recurrent nova T Pyxidis
M. Pavana, Ramya M Anche, G. C. Anupama +2
We study the spectroscopic and ionized structural evolution of T Pyx during its 2011 outburst, and also study the variation in degree of polarization during its early phase. Optica…
V2676 Oph: Estimating physical parameters of a moderately fast nova
Ashish Raj, M. Pavana, U. S. Kamath +2
Using our previously reported observations, we derive some physical parameters of the moderately fast nova V2676 Ophiuchi 2012 # 1. The best-fit CLOUDY model of the nebular spectru…
Breaking the habit - the peculiar 2016 eruption of the unique recurrent nova M31N 2008-12a
M. Henze, M. J. Darnley, S. C. Williams +70
Since its discovery in 2008, the Andromeda galaxy nova M31N 2008-12a has been observed in eruption every single year. This unprecedented frequency indicates an extreme object, with…
