p-modes in and away from a sunspot
Brajesh Kumar, R. Jain, S. C. Tripathy +2
A time series of GONG Dopplergrams for the period 10-14 May 1997 from Udaipur and Big Bear sites has been used to measure the velocity fluctuations in the sunspot (NOAA active regi…
Star formation along a misaligned bar in the peculiar starburst galaxy Mkn 439
Aparna Chitre, U. C. Joshi, S. Ganesh
We report the detection of massive star formation along a bar in the peculiar starburst galaxy Mkn 439. We present optical B, R and H_alpha + [NII] emission line images as well as…
Photometric studies of some starburst galaxies
Aparna Chitre, U. C. Joshi
We present the results of a detailed morphological analysis of ten starburst galaxies selected from the Markarian catalogue of uv-excess objects. CCD surface photometry of these ga…
ISOGAL Survey of Baade's Windows in the Mid-infrared
I. S Glass, S. Ganesh, C. Alard +6
The ISOGAL mid-infrared survey of areas close to the Galactic Plane aims to determine their stellar content and its possible bearing on the history of the Galaxy. The NGC6522 and S…
Shocked Molecular Hydrogen from RNO91
M. S. Nanda Kumar, B. G. Anandarao, C. J. Davis
We report the detection of the H2 v=1-0 S(1) line at 2.122um, from RNO91 in the L43 dark cloud, which is known to be a T Tauri star surrounded by a 1700AU disk structure (containin…
Effective Radii and Color Gradients in Radio Galaxies
Ashish Mahabal, Ajit Kembhavi, Patrick J. P. McCarthy
We present de Vaucouleurs' effective radii in B and R bands for a sample of Molonglo Reference Catalogue radio galaxies and a control sample of normal galaxies. We use the ratio of…
