Optical photometric and polarimetric investigation of NGC 1931
A. K. Pandey, C. Eswaraiah, Saurabh Sharma +7
We present optical photometric and polarimetric observations of stars towards NGC 1931 with the aim to derive the cluster parameters such as distance, reddening, age and luminosity…
Optical and Near-infrared survey of the stellar contents associated with the star-forming Complex Sh2-252
Jessy Jose, A. K. Pandey, K. Ogura +8
We present the analyses of the stellar contents associated with the HII region Sh2-252 using UBVRI photometry, slit and slitless spectroscopy along with the NIR data from 2MASS for…
Digitized archive of the Kodaikanal images: Representative results of solar cycle variation from sunspot area determination
B. Ravindra, T. G. Priya, K. Amareswari +3
Photographic images are valuable data resources for studying long term changes in the solar magnetic field and its influence on the Earth's climate and weather. We digitized more t…
Polarimetric studies of carbon stars at high Galactic latitude
Aruna Goswami, Drisya Karinkuzhi
Very little is known about the polarimetric properties of CH stars and carbon-enhanced metal-poor (CEMP) stars, although many of these objects have been studied in detail both phot…
Rotation rates of the coronal holes and their probable anchoring depths
K. M. Hiremath, M. Hegde
For the years 2001-2008, we use full-disk, SOHO/EIT 195 calibrated images to determine latitudinal and day to day variations of the rotation rates of coronal holes. We estimate…
Planets in the Early Universe
Yu. A. Shchekinov, M. Safonova, J. Murthy
Several planets have recently been discovered around old metal-poor stars, implying that these planets are also old, formed in the early Universe. The canonical theory suggests tha…
