Probing Flare-Associated Eruptions on AB Doradus via X-ray Absorption Variations
Shweta Didel, Jeewan C Pandey, Abhishekh K Srivastava
In this work, we investigate eruptive phenomena associated with X-ray flares on AB Doradus using observations from XMM-Newton. Our aim is to detect such events with the help of con…
V515 And: An Intermediate Polar in the Period Gap Exhibiting Outbursts
Srinivas M Rao, Jeewan C Pandey, Nikita Rawat +4
Using long-term observations from the Transiting Exoplanet Survey Satellite (TESS) along with spectroscopic observations from the 3.6 m Devasthal Optical Telescope (DOT), we presen…
Observations of Binary Stars with the 1.3-m Devasthal Fast Optical Telescope Using Speckle Interferometry: An Attempt
Km Nitu Rai, Arjun Dawn, Neelam Panwar +3
We present a feasibility study exploring the implementation of optical interferometry and speckle techniques with the 1.3-m Devasthal Fast Optical Telescope (DFOT) at ARIES, which…
Long-term Optical Photometry of V709 Cas Using TESS : Refined Periods and Accretion Geometry
Srinivas M Rao, Jeewan C Pandey, Nikita Rawat +2
Utilizing high-cadence and long-term optical photometry from the Transiting Exoplanet Survey Satellite (TESS ), we conducted a time-resolved timing analysis of the Intermediate Pol…
Precise Timing Analysis of Four Magnetic Cataclysmic Variables with TESS
Srinivas M Rao, Jeewan C Pandey, Nikita Rawat +2
We analysed high time-resolution optical photometric data from the Transiting Exoplanet Survey Satellite (TESS) to study the timing behaviour of four intermediate polar-like object…
Long-term investigation of an open cluster Berkeley 65
Tarak Chand, Saurabh Sharma, Koshvendra Singh +7
We present a decade-long investigation of a poorly studied cluster, Berkeley 65 (Be 65), using deep optical data from the telescopes of ARIES, Nainital Observatory. We estimate its…
