Increasing evidence suggests that the mechanism(s) for heating the chromospheres of the coolest red giants may be quite different from those responsible for heating in solar-type stars, but little progress toward a quantitative test of this important idea has been made, both because of the scarcity of suitable observations and the difficulty of ...

This article reports that astronomers have found an exoplanet that likely survived the red giant phase of its parent star. Named V391 Pegasi, it belongs to a class of subdwarf stars that flicker. Researchers noticed the regularity of the flickering and says it is a planet at least 3 times bigger than Jupiter.

Axion bremsstrahlung in red giants
Physical Review D, 1990We calculate the bremsstrahlung emission rate of axions from a degenerate but weakly coupled plasma, using a Debye structure factor to take account of the nuclei correlations. This result pertains to axion emission from red giants near the helium flash and thus could be used to make a previous bound precise which involves the suppression of helium ...

In 2012, we published a paper in the Journal of Critical Globalization Studies titled 'Imperialism and Financialism: The Story of a Nexus'. Our topic was the chameleon-like Marxist notion of imperialism and how its different theories related to finance.

Expanding, cool envelopes around red giants were detected many years ago when Adams and McCormack (1935) discovered that on high dispersion spectra of ∝ Ori, ∝1 Her, o Cet and e Peg the stronger resonance lines showed violet displaced absorption cores which could be explained by an expanding gaseous envelope.

Basic concepts in the theory of astronomical masers which are necessary for the discussion of red giant masers are introduced. Maser radiation from late type stars is then discussed in detail with special emphasis on SiO masers as probes of the stellar atmosphere and OH masers as a tool for studying the mass loss process and the circumstellar shell.
