  • Investigating star-formation activity in Sh 2-61 H II region 
    PANDEY, RAKESH; SHARMA, SAURABH; DEWANGAN, LOKESH; VERMA, AAYUSHI; BAUG, TAPAS; KAUR, HARMEEN; GHOSH, ARPAN (Journal Astrophysical Astronomy, 2023-08)
    Using multi-wavelength data sets, we studied the star-formation activity in Hii region Sh 2-61 (hereafter S61). We identified a clustering in the region and estimated the membership using the Gaia proper motion data. The ...
  • Optical spectroscopy of Gaia detected protostars with DOT: Can we probe protostellar photospheres? 
    NARANG, MAYANK; MANOJ, P.; TYAGI, HIMANSHU; NAYAK, PRASANTA K.; SHARMA, SAURABH; SURYA, ARUN; BANERJEE, BIHAN; MATHEW, BLESSON; GHOSH, ARPAN; VERMA, AAYUSHI (Journal Astrophysical Astronomy, 2023-11)
    Optical spectroscopy offers the most direct view of the stellar properties and the accretion indicators. Standard accretion tracers, such as Hβ, Hα and Ca II triplet lines, and most photospheric features fall in the optical ...
  • Quiescence of an outburst of a low-mass young stellar object: LDN1415-IRS 
    SINGH, KOSHVENDRA; OJHA, DEVENDRA K.; NINAN, JOE P.; SHARMA, SAURABH; GHOSH, SUPRIYO; GHOSH, ARPAN; BHATT, BHUWAN C.; SAHU, DEVENDRA K. (Journal Astrophysical Astronomy, 2023-06)
    LDN1415-IRS, a low-mass young stellar object (YSO), went into an outburst between 2001 and 2006, illuminating a surrounding nebula, LDN1415-Neb. LDN1415-Neb was found to have brightened by I = 3.77 mag by April 2006. The ...
