A tale of three cataclysmic variables with distinct superhumps
Arti Joshi, Claus Tappert, Márcio Catelan +2
We present the TESS observations of CRTS J110014.7+131552, SDSS J093537.46+161950.8, and [PK2008] HalphaJ130559. Among them, a superoutburst is observed in CRTS J110014.7+131552 wh…
[PK2008] HalphaJ115927 and IGR J14091-6108: Two new intermediate polars above the period gap
Arti Joshi
This study presents a detailed timing analyses of two cataclysmic variables (CVs), [PK2008] HalphaJ115927 and IGR J14091-610, utilizing the optical data from the Transiting Exoplan…
The Dusty Aftermath of a Rapid Nova: V5579 Sgr
A. Raj, M. S. Bisht, F. M. Walter +10
V5579 Sgr was a fast nova discovered in 2008 April 18.784 UT. We present the optical spectroscopic observations of the nova observed from the Castanet Tolosan, SMARTS and CTIO obse…
Unveiling the nature of two dwarf novae: CRTS J080846.2+313106 and V416 Dra
Arti Joshi, Márcio Catelan, Simone Scaringi +8
We present the analysis of optical photometric and spectroscopic observations of two non-magnetic cataclysmic variables, namely CRTS J080846.2+313106 and V416 Dra. CRTS J080846.2+3…
Identifying reliable periods in 2MASS J09213414-5939068, IGR J16167-4957, and V667 Pup
Arti Joshi
Detailed timing analyses of three cataclysmic variables, namely 2MASS J092134145939068, IGR J161674957, and V667 Pup are carried out using the long-baseline and high-cadence…
