Stellar Disks in Early-Type Galaxies

1992
Correlation between isophotal and physical parameters suggests that elliptical galaxies are divided into two main classes: the ‘boxy’ Es, which are likely the result of a strong environmental evolution (mergers), and the ‘disky’ Es, which represent the continuation of the SO sequence toward vanishing disk-to-bulge ratios.

Local stability in heliac type stellarators

Nuclear Fusion, 1997
A study of the stability limits for ideal ballooning modes in helical axis stellarators (heliac type stellarators) has been performed. Specific configurations similar to those of the TJ-II heliac have been taken, having a deep magnetic well and almost zero shear, which is characteristic for a heliac.

Models of late-type stellar photospheres

The Astronomy and Astrophysics Review, 1994
In this review we discuss recent work and progress in the modelling of photospheres of stars of spectral types F and later. Special emphasis is laid on advances as regards the consideration of atomic and molecular blanketing, non-LTE and convection and other dynamic processes.

Stellar Populations in BL Lac type Objects

Astrophysics and Space Science, 2001
The relationship between an Active Galactic Nucleus (AGN) and its host galaxy is a crucial question in the study of galaxy evolution. We present an estimate of the stellar contribution in a sample of low luminosity BL Lac type objects. We have performed stellar population synthesis for a sample of 19 objects selected from Marcha et al. (1996, MNRAS 281

Stellar evolution and late type stars

Astrophysics and Space Science, 1995
The M, S and C stars may be placed in an evolutionary sequence on the basis of direct observation of the spectroscopic transitions on the AGB of rich intermediate-age clusters in the Magellanic Clouds, but some S and C stars cannot be accounted for in this way.

Statistical criteria of stellar population types

Symposium - International Astronomical Union, 1966
In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to ...
