Sh2-138: physical environment around a small cluster of massive stars

Baug, T; Ojha, D. K; Dewangan, L. K; Ninan, J. P; Bhatt, B. C; Ghosh, S. K; Mallick, K. K (Oxford University Press on behalf of the Royal Astronomical Society, 2015-12-21)

We present a multiwavelength study of the Sh2-138, a Galactic compact H II region. The data comprise of optical and near-infrared (NIR) photometric and spectroscopic observations from the 2-m Himalayan Chandra Telescope, ...
Star Formation Activity in the Galactic H II Region Sh2-297

Mallick, K. K; Ojha, D. K; Samal, M. R; Pandey, A. K; Bhatt, B. C; Ghosh, S. K; Dewangan, L. K; Tamura, M (IOP Publishing, 2012-11-01)

We present a multiwavelength study of the Galactic H II region Sh2-297, located in the Canis Major OB1 complex. Optical spectroscopic observations are used to constrain the spectral type of ionizing star HD 53623 as B0V. ...
Star Formation and Evolution of Blister-type H II Region Sh2-112

Panwar, N; Sharma, S; Ojha, D. K; Baug, T; Dewangan, L. K; Bhatt, B. C; Pandey, R (IOP Publishing, 2020-12-10)

We report the observational findings of the Sh2-112 H ii region by using the multiwavelength data analysis ranging from optical to radio wavelengths. This region is powered by the massive O8V-type star BD +45 3216. The ...
