Places of formation of nineteen nearby classical Cepheids

Joshi, U. C (Astronomical Society of India, 1982-09)

Places of formation of 10 nearby classical Cepheids have been computed in a model of our Galaxy which has axisymmetric and spiral-like components. For the axisymmetric components Schmidt's (1965) model is used, and spiral-like ...
A Revised Calibration of the M-V-W(O I 7774) Relationship using Hipparcos Data: Its Application to Cepheids and Evolved Stars

Ferro, A. A; Giridhar, S; Arellano, E. R (Instituto de Astronomía, Universidad Nacional Autónoma de México, 2003-04)

A new calibration of the MV-W(O I 7774) relationship has been calculated using better reddening and distance estimates for a sample of 27 calibrator stars of spectral types A to G, based on accurate parallaxes and proper ...
Spectral Analysis of Selected Cepheids and the Galactic Distribution of Metalicity

Giridhar, S (Indian Institute of Astrophysics, Bangalore, 1982-10)
Stellar populations in the magellanic clouds

Subramanian, S; Subramaniam, A (Astronomical Society of India, 2013)

The structural parameters of the Large Magellanic Cloud and the Small Magellanic Cloud are derived from the study of di erent stellar populations, such as, Cepheids (age 100 Myr), Red Clump stars (age 2-9 Gyr) and RR ...
