Abundance analysis of the long period southern Cepheid RZ Vel

Giridhar, S; Goswami, A; Arellano Ferro, A (Indian Academy of Sciences, 1991-03)

An abundance analysis is conducted for the long period (P = 20.4 days), young classical Cepheid RZ Vel, a recognized member of an OB association. The results of the analysis are compared with the photometric study by Eggen ...
Classical Cepheids and the local chemical inhomogeneities in the galactic disc

Giridhar, S (1986-06)

Places of formation have been derived for a sample of 23 Cepheids with well-determined atmospheric abundances in an attempt to study the chemical inhomogeneities in the local interstellar medium. The abundance data available ...
Spectrophotometric studies of CO Cephei

Shylaja, B. S (Indian Academy of Sciences, 1986-09)

Spectrophotometric and spectroscopic observations of CQ Cep, the shortest-period binary with a WN component, are presented. Excepting the N V 4603 A, the fluxes of all other emission lines show enhancement at minima. They ...
Spectroscopic observations of Nu Centauri

Ashoka, B. N; Surendiranath, R; Kameswara Rao, N (Copernicus Foundation for Polish Astronomy, 1985)

Presented are radial-velocity observations of the single-line spectroscopic binary and Beta Cephei-type variable Nu Cen, obtained in the period 1983-1984. New orbital elements have been determined by combining these ...
