The reddened open cluster NGC7419 is believed to have a very high fraction of Be stars and present an exceptionally high number of red supergiants (five for no...
A spectroscopic view of stellar populations in bulges of low surface brightness galaxies .
We present the radial profiles of the age, metallicity and alpha /Fe enhancement of the stellar populations in the bulge-dominated region for a sample of eight...
A Spitzer search for transiting exoplanets around ultra-cool dwarf stars viewed equator-on
Exoplanet population studies indicate that small rocky planets may be common around very low-mass stars and brown dwarfs: "ultra-cool" dwarfs. Temperate rocky...
A Statistical Comparison of the Near Infrared Emission with the Ha Emission from the HII regions of NGC4321, NGC4736 and NGC4254
We report on our ongoing project "Statistical studies of HII regions in the nearby extra-galaxies". In this report we present the overview of our detailed study...
A Statistical Comparison of the Near Infrared Emission with the Hα Emission from the HII regions of NGC4321, NGC4736 and NGC4254
We report on our ongoing project ``Statistical studies of HII regions in the nearby extra-galaxies''. We present an overview of our detailed study of warm dust...
A Statistical Study of Circumnuclear Morphology of Sigma-Drop Galaxies
Sigma-drop galaxies are characterized by a drop in the stellar velocity dispersion in their centers. One of the most likely theories to explain this phenomenon...
A steep bandpass interference filter with FWHM 11nm centered at 1254nm for studying Lyman Alpha signatures of highly redshifted galaxies
The presented new 1% narrowband filter centered at 1254nm with a FWHM of 11nm required and achieved excellent maximum transmission and deep out of band blocking...
A Stellar Model-fitting Pipeline for Solar-like Oscillations
Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon...
