Post-outburst evolution of bonafide FUor V2493 Cyg: A Spectro-photometric monitoring
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +11
We present here the results of eight years of our near-simultaneous optical/near-infrared spectro-photometric monitoring of bonafide FUor candidate `V2493 Cyg' starting from 2013 S…
Spectroscopy of 9 eruptive young variables using TANSPEC
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +8
In recent times, 3.6m Devasthal Optical Telescope (DOT) has installed an optical to near infra-red spectrograph, TANSPEC, which provides spectral coverage from 0.55-2.5 microns. Us…
Teutsch 76: a Deep Near-Infrared Study
Saurabh Sharma, Lokesh Dewangan, Neelam Panwar +9
We have performed a detailed analysis on the Teutsch 76 (T76) open cluster using the deep near-infrared (NIR) observations taken with the TANSPEC instrument mounted on the 3.6m Dev…
Gaia 20eae: A newly discovered episodically accreting young star
Arpan Ghosh, Saurabh Sharma, Joe. P. Ninan +18
The Gaia Alert System issued an alert on 2020 August 28, on Gaia 20eae when its light curve showed a 4.25 magnitude outburst. We present multi-wavelength photometric and spec…
Photometric variability of the pre-main sequence stars towards the Sh 2-190 region
Tirthendu Sinha, Saurabh Sharma, Neelam Panwar +7
We present the results from our time-series imaging data taken with the 1.3m Devasthal fast optical telescope and 0.81m Tenagara telescope in , , bands covering a…
Further milliarcsecond resolution results on cool giants and binary stars from lunar occultations at Devashtal
A. Richichi, Saurabh Sharma, T. Sinha +5
We report on 26 lunar occultation events observed in the context of a program started at Devasthal in 2017. In addition to the customary observations with the 1.3-m telescope, we r…
Variable stars in the Sh 2-170 HII region
Tirthendu Sinha, Saurabh Sharma, A. K. Pandey +7
We present multi-epoch deep (20 mag) ~band photometric monitoring of the Sh 2-170 star-forming region to understand the variability properties of pre-main-sequence (PM…
Stellar cores in the Sh 2-305 H II region
Rakesh Pandey, Saurabh Sharma, Neelam Panwar +6
Using our deep optical and near-infrared photometry along with multiwavelength archival data, we here present a detailed study of the Galactic H II region Sh 2-305, to understand t…
