Proceedings of the International Astronomical Union, 2011 AbstractThe longest-known class of pulsating variable stars, namely pulsating red giants, is also the one that involves the most complex physical processes. Pulsation, mass loss, nuclear synthesis, mixing, atmospheric and circumstellar chemistry and dust formation all interrelate with one another and make both the observational studies and the ...

Frontiers in Genetics, 2023 The changes in the expression of genes related to digestion and metabolism may be various in different dietary mammals from juvenile to adult, especially, the giant panda (Ailuropoda melanoleuca) and red panda (Ailurus fulgens), which were once ...

Metallicities of Globular Clusters m3 and m5 from VI CCD Photometry [PDF]
Journal of Astronomy and Space Sciences, 2000 To derive the metallicities of M3 and M5, we used the shape of red giant branch, horizontal branch magnitude, and red giant branch bump on the (V - I) - V color magnitude diagrams.

TESS asteroseismology of the Kepler red giants [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACTRed giant asteroseismology can provide valuable information for studying the Galaxy as demonstrated by space missions like CoRoT and Kepler. However, previous observations have been limited to small data sets and fields of view. The TESS mission provides far larger samples and, for the first time, the opportunity to perform asteroseimic ...

Why red giants are giant [PDF]
Monthly Notices of the Royal Astronomical Society, 1989 Four primary causes for the giantness of red giants are identified: (1) the opacity law in the lower envelope; (2) the abrupt molecular weight change across the shell; (3) convection or electron degeneracy in hydrogen-exhausted cores above a certain mass; and (4) approximate thermostatic control of the core by simultaneous hydrogen and helium burning ...

Rotational Shearing Interferometer in Detection of the Super-Earth Exoplanets
Applied Sciences, 2022 The astronomers and the general population are fascinated with the problem of exoplanet detection. By far the largest number of detected planets are the so-called Super Earths, relatively cold planets orbiting a large, red giant star, with diameters up ...

Exoplanets around Red Giants: Distribution and Habitability
Galaxies, 2023 As the search for exoplanets continues, more are being discovered orbiting Red Giant stars. We use current data from the NASA Exoplanet Archive to investigate planet distribution around Red Giant stars and their presence in the host’s habitable zone.

Red Giants observed with CoRoT [PDF]
AIP Conference Proceedings, 2009 Observations of red (G-K)-giant stars with the CoRoT satellite provide unprecedented information on the stochastically excited oscillations in these stars. The long time series of nearly uninterrupted high-cadence and high-precision photometry revealed the presence of non-radial modes with long lifetimes, which opens the possibility to perform ...
