Red giant stars as standard candles
2022This thesis introduces two new extragalactic distance determination methods; the first uses the median magnitude of carbon-rich asymptotic giant branch stars (CS), while the second uses the combined luminosity function of the red-giant branch (RGB) and oxygen-rich asymptotic giant branch stars (AGB). The sample of CS and RGB+AGB stars are selected from

Pulsational Stability of Red Giant Stars
AIP Conference Proceedings, 2009We revisit the problem of pulsational stability of radial and strongly trapped non‐radial modes of red giant stars. We present the results of numerical computations of oscillation properties of a 2.03 M⊙ evolutionary stellar model along the AGB. We examine the pulsational stability by taking into account the effect of perturbation of convective flux ...

Transport processes in red giant stars
EAS Publications Series, 2006Low-mass stars ( ๏ ) exhibit, at all the stages of their evolution, signatures of processes that require challenging modeling beyond the standard stellar theory. In this paper we focus on their peculiarities while they climb the red giant branch (RGB).

Why Do Stars Become Red Giants?
1981The reasons why main sequence dwarfs evolve into red giants have been known for 30 or 40 years, but there are two excuses for a brief rediscussion of the problem. Firstly, there are quite a number of misconceptions around. Secondly, even the correct physical processes are not obviously correct; is there some reasonably simple model, not based on ...

2008
A discussion is presented of the observations of circumstellar envelopes around late-type giant stars. The results are treated in two broad categories. First, there are extensive surveys which provide a few basic parameters of the flows (vexp, dM/dt and/or abundance information). These indicate the importance of rapid mass-loss to stellar evolution and

Energy liberation in red giant stars
Physica, 1943Summary The theory of Gamow and Teller about the energy liberation in red giants is criticized. It is shown, that the rate of evolution predicted by this theory is in contradiction with the secular variations in the periods of Cepheids. The reverse conclusions, at which Greenfield arrived, are shown to be erroneous.

The Photospheres of Red-Giant Stars
1981Various empirical methods for studying the physical properties of red-giant photospheres are illustrated by examples of recent studies. Certain branches of the theory of late-type photospheres, where progress has recently been made or will probably be made within a near future, are commented on.
