Evolution and the period-luminosity relation for red supergiants in the Magellanic Clouds [PDF]

open access: yes, 2013
Excitation of radial pulsations in red supergiants of Magellanic Clouds is investigated using the stellar evolution calculations and the self-consistent solution of the equations of radiation hydrodynamics and turbulent convection. The stars with initial

Neglected cutaneous skin malignancy: A patient with concurrent giant basal cell carcinoma and melanoma

open access: yesSkin Health and Disease, Volume 1, Issue 4, December 2021., 2021
Abstract Background Giant basal cell carcinomas (BCCs) are a rare subtype of BCC that grow to be greater than 5 cm in diameter. With the increase in size, there is a corresponding increase in metastatic rate and state of local invasion, with a clinical morphology that can be hard to differentiate from other subtypes of cutaneous malignancy.

A third cluster of red supergiants in the vicinity of the massive cluster RSGC3 [PDF]

open access: yes, 2012
Recent studies have shown that the area around the massive, obscured cluster RSGC3 may harbour several clusters of red supergiants. In this paper, we analyse a clump of photometrically selected red supergiant candidates 20' south of RSGC3 in order to ...

MODELS OF CIRCUMSTELLAR MASERS IN BIPOLAR OUTFLOWS

open access: yesOdessa Astronomical Publications, 2017
Sources of molecular maser radio emission in envelopes of late-type variable stars (red giants and supergiants) are considered. Radio and optical data on asymmetry of mass loss process in red giants are briefly reviewed.

A catalog of known Galactic K-M stars of class I, candidate RSGs, in Gaia DR2 [PDF]

open access: yes, 2019
We investigate individual distances and luminosities of a sample of 889 nearby candidate red supergiants with reliable parallaxes (plx/plxerr > 4 and RUWE < 2.7) from Gaia DR2. The sample was extracted from the historical compilation of spectroscopically

Physical Properties of Red Supergiants [PDF]

open access: yesNew Astronomy Reviews, 2010
Red supergiants (RSGs) are an evolved He-burning phase in the lifetimes of moderately high mass (10 - 25 solar mass) stars. The physical properties of these stars mark them as an important and extreme stage of massive stellar evolution, but determining these properties has been a struggle for many years. The cool extended atmospheres of RSGs place them

Supernova Shock Breakout from a Red Supergiant [PDF]

open access: yesScience, 2008
Massive stars undergo a violent death when the supply of nuclear fuel in their cores is exhausted, resulting in a catastrophic “core-collapse” supernova. Such events are usually only detected at least a few days after the star has exploded. Observations of the supernova SNLS-04D2dc with the Galaxy Evolution Explorer space telescope reveal a radiative ...
