Long-term chromospheric activity of non-eclipsing RS CVn-type stars
Andrea P. Buccino, Pablo J. D. Mauas
Context. The IUE database provides a large number of UV high and low-resolution spectra of RS CVn-type stars from 1978 to 1996. In particular, many of these stars were monitored co…
Solar Forcing of the Streamflow of a Continental Scale South American River
P. J. D Mauas, E. Flamenco, A. P. Buccino
Solar forcing on climate has been reported in several studies although the evidence so far remains inconclusive. Here, we analyze the stream flow of one of the largest rivers in th…
Possible chromospheric activity cycles in II Peg, UX Ari and V711 Tau
Andrea P. Buccino, Pablo J. D. Mauas
We study the Mount Wilson indices we obtained indirectly from IUE high and low resolution spectra of the RS CVn-type systems II Peg (K2IV), UX Ari (K0IV+G5V) and V711 Tau (K1IV+G5V…
Mg II h + k emission lines as stellar activity indicators of main sequence F-K stars
Andrea P. Buccino, Pablo J. D. Mauas
The main purpose of this study is to use the IUE spectra in the analysis of magnetic activity of main sequence F-K stars. Combining IUE observations of MgII and optical spectroscop…
UV habitable zones around M stars
Andrea P. Buccino, Guillermo A. Lemarchand, Pablo J. D. Mauas
During the last decade, there was a paradigm-shift in order to consider terrestrial planets within liquid-water habitable zones (LW-HZ) around M stars, as suitable places for the e…
Ultraviolet Radiation Constraints around the Circumstellar Habitable Zones
Andrea P. Buccino, Guillermo A. Lemarchand, Pablo J. D. Mauas
Ultraviolet radiation is known to inhibit photosynthesis, induce DNA destruction and cause damage to a wide variety of proteins and lipids. In particular, UV radiation between 200-…
