Expanding chromospheres of late G and K supergiants

Mallik, S. G. V (Royal Astronomical Society, 1986-09)

The radiative transfer problem in non-LTE moving atmospheres has been explicitly solved for Hα line profiles. These computations have been done for a schematic model of the line-forming region over a wide range of optical ...
The far-infrared (IRAS) excess in luminous F-G stars

Pottasch, S. R; Parthasarathy, M (European Southern Observatory, 1988-03)

The far-infrared IRAS excesses are found in ten luminous F-G stars. The far-IR fluxes from these stars are due to large amounts of dust around them. The far-IR flux distribution, far-IR luminosities and dust masses are ...
A new discussion on the M(v) - W(O I 7774 A) relationship for F-G stars in the light of high-resolution data

Arellano Ferro, A; Giridhar, S; Goswami, A (Royal Astronomical Society, 1991-05)

High-resolution CCD data and a large group of F-G stars of fundamentally determined distances are used here to investigate the intrinsic nature of the M(v) - W(O I) relation and the effect of other atmospheric parameters ...
