SELECTED TOPICS IN THE EVOLUTION OF LOW-MASS STARS
(S/EDITORIAL, 2013)
Low-mass stars play a key role in many different areas of astrophysics. In this
article, I provide a brief overview of the evolution of low-mass stars, and discuss some of
the uncertainties and problems currently affecting ...

Analysis of hourly global, direct and diffuse solar radiations attenuation as a function of optical air mass
(Elsevier B.V., 2014-01-01)
The objective of this work is to verify the attenuation caused by atmospheric constituents through the relationship between global, direct and diffuse solar radiation with respect to optical air mass. The optical air mass ...
Serendipitous observation of a coronal mass ejection during the total solar eclipse of 14 December 2020
(S. A. Cannas, 2021-08-05)
We report observations of the total solar eclipse of 14 December 2020, during which a coronal mass ejection was seen to propagate. A comprehensive set of photographs covering a high dynamic range of exposure enabled ...
Active Region-Based Full-Disc Solar Image Hashing
(2020-01-01)
The main components of the Solar activity are solar flares, coronal mass ejections, high-speed solar wind, and solar energetic particles. Solar flares impact the Earth when they occur on the side facing our planet.
Sunset or sunrise? Understanding the barriers and options for the massive deployment of solar technologies in Chile
(Elsevier, 2018)
The use of solar technologies should proliferate in Chile as half of the country has a solar irradiance (GHI) above 5 kWh/(m(2)d). Moreover, the Atacama Desert exhibits further advantageous conditions with 7 kWh/(m(2)d), ...
Solar twins in M 67: evolutionary status and lithium abundance
(EDP SCIENCES S A, 2011)
Aims. We determine the age and mass of the three best solar twin candidates in open cluster M 67 through lithium evolutionary models. Methods. We computed a grid of evolutionary models with non-standard mixing at metallicity ...
Coronal Transient Events During Two Solar Minima: Their Solar Source Regions and Interplanetary Counterparts
(Springer, 2011-12)
In the frame of two coordinated observational and research efforts, two full solar rotations were investigated in the times of two distinct solar minima. These two campaigns were dubbed Whole Sun Month (WSM; 10 August – 8 ...
