Near-Infrared Photometry and Radio Continuum Study of the Massive Star Forming Regions IRAS 21413+5442 and IRAS 21407+5441
B. G. Anandarao, V. Venkata Raman, S. K. Ghosh +2
IRAS 21413+5442 and IRAS 21407+5441 are two massive star forming regions of high luminosity, likely associated with each other. Near-infrared photometry on these two IRAS sources w…
Infrared Spectroscopic Study of a Selection of AGB and Post-AGB Stars
V. Venkata Raman, B. G. Anandarao
We present here near-infrared spectroscopy in the H and K bands of a selection of nearly 80 stars that belong to various AGB types, namely S type, M type and SR type. This sample a…
Post-Outburst Phase of McNeil's Nebula (V1647 Orionis)
D. K. Ojha, S. K. Ghosh, A. Tej +11
We present a detailed study of the post-outburst phase of McNeil's nebula (V1647 Ori) using optical B,V,R,I and NIR J,H,K photometric and low resolution optical spectroscopic obser…
SS 433: Results of a Recent Multi-wavelength Campaign
Sandip K. Chakrabarti, B. G. Anandarao, S. Pal +8
We conducted a multi-wavelength campaign in September-October, 2002, to observe SS 433. We used 45 meter sized 30 dishes of Giant Meter Radio Telescope (GMRT) for radio observation…
Possible Photometric Evidence of Ejection of Bullet Like Features in the Relativistic Jet source SS433
Sandip K. Chakrabarti, S. Pal, A. Nandi +2
SS433 is well-known for its precessing twin jets having optical bullets inferred through {\it spectroscopic} observation of lines. Recently, Chakrabarti et al. (2002) describ…
Detection of Knots and Jets in IRAS 06061+2151
B. G. Anandarao, A. Chakraborty, D. K. Ojha +1
We report detection of a Young Stellar Object with an evidence for an outflow in the form of knots in the molecular hydrogen emission line (2.121 micron) towards the massive star f…
