Challenges In Stellar Pulsation
2010Ever since some stars were found to pulsate in the early 20th century, stellar pulsation has been a major topic in astronomy and astrophysics. The huge amount of data recently available from observational surveys, new discoveries from space missions and studies of pulsating stars in low-metallicity environments have opened new perspectives and ...

Stellar Pulsations and Stellar Evolution: Conflict, Cohabitation, or Symbiosis?
2012While the analysis of stellar pulsations allows the determination of current properties of a star, stellar evolution models connect it with its previous history. In many cases results from both methods do not agree. In this review some classical and current cases of disagreement are presented.

Inversion method in stellar pulsation
AIP Conference Proceedings, 2007This is a presentation of the asteroseismological method (ROMOSC) implemented in the Bucharest Observatory to be used in the CoRoT mission. We will also present a calibration of this method with the similar one implemented in the MOST mission in the case of the star η Boo.

Physical mechanisms in stellar pulsations
The Journal of the Acoustical Society of America, 1985Stars evolve from their births to their deaths by converting their store of hydrogen to helium, and then much of this helium is fused to heavier elements such as carbon, oxygen, and up to iron. During this evolution, the stellar mass may decrease by a stellar wind mass loss, the radius usually greatly increases, and the radiation luminosity emitted at ...

Excitation of Stellar Pulsations
2012In this review I present an overview of our current understanding of thephysical mechanisms that are responsible for the excitation of pulsations in stars withsurface convection zones. These are typically cooler stars such as the Delta Scuti stars,and stars supporting solar-like oscillations.
