Asteroseismology of sz lyn using multi-band high time resolution photometry from ground and space
J. Adassuriya, S. Ganesh, J. L. Gutierrez +4
We report the analysis of high temporal resolution ground and space based photometric observations of SZ Lyncis, a binary star one of whose components is a high amplitude Scuti…
EMPOL: an EMCCD based optical imaging polarimeter
Shashikiran Ganesh, Archita Rai, Aravind K +12
An Andor 1K 1K EMCCD detector has been used to develop an optical imaging polarimeter for use at the Cassegrain focus of 1.2 m telescope of PRL. The optics is derived from…
Ionic emissions in comet C/2016 R2 (Pan-STARRS)
Kumar Venkataramani, Shashikiran Ganesh, Kiran S. Baliyan
We carried out observations of a peculiar comet, C/2016 R2 (Pan-STARRS), using a low resolution spectrograph mounted on the 1.2m telescope at Mount Abu Infrared Observatory, India.…
Time and phase resolved optical spectra of potentially hazardous asteroid 2014 JO25
Kumar Venkataramani, Shashikiran Ganesh, Archita Rai +3
The asteroid 2014 JO25, considered to be "potentially hazardous" by the Minor Planet Center, was spectroscopically followed during its close-Earth encounter on 19th and 20th of Apr…
High accuracy measurement of gravitational wave back-reaction in the OJ287 black hole binary
Mauri J. Valtonen, L. Dey, R. Hudec +16
Blazar OJ287 exhibits large thermal flares at least twice every 12 years. The times of these flares have been predicted successfully using the model of a quasi-Keplerian eccentric…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
