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 ...

Metallicities of Globular Clusters m3 and m5 from VI CCD Photometry [PDF]
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.

Gamma-ray flares from red giant/jet interactions in AGN [PDF]
Non-blazar AGN have been recently established as a class of gamma-ray sources. M87, a nearby representative of this class, show fast TeV variability on timescales of a few days. We suggest a scenario of flare gamma-ray emission in non-blazar AGN based on

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 ...

Why red giants are giant [PDF]
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 ...

This paper reports the estimated stellar parameters of 1153 Kepler red giant branch stars determined with asteroseismic modeling. We use radial-mode oscillation frequencies, gravity-mode period spacings, Gaia luminosities, and spectroscopic data to ...

Characterisation of red-giant stars in the public Kepler data
The first public release of long-cadence stellar photometric data collected by the NASA Kepler mission has now been made available. In this paper we characterise the red-giant (G-K) stars in this large sample in terms of their solar-like oscillations. We

Rotational Shearing Interferometer in Detection of the Super-Earth Exoplanets
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 ...
