Mass Loss Evolution in the EUV Low Corona from SDO/AIA Data
Fernando M. López, Hebe Cremades, Federico A. Nuevo +2
We carry out an analysis of the evacuated mass from three coronal dimming regions observed by the {\it Atmospheric Imaging Assembly} (AIA) on board the {\it Solar Dynamics Observat…
A possible long-term activity cycle for ι Horologii: First results from the HKα & SPI-HKα projects
Matías G. Flores, Andrea P. Buccino, Carlos E. Saffe +1
To detect stellar activity cycles and study the possible star-planet interactions (SPI's), we have developed both HK and SPI-HK projects since 1999 and 2012 respectively. In…
First Simultaneous Views of the Axial and Lateral Perspectives of a Coronal Mass Ejection
I. Cabello, H. Cremades, L. Balmaceda +1
The different appearances exhibited by coronal mass ejections (CMEs) are believed to be in part the result of different orientations of their main axis of symmetry, consistent with…
Spectroscopic signatures of magnetospheric accretion in Herbig Ae/Be stars. I. The case of HD101412
M. Schöller, M. A. Pogodin, J. A. Cahuasqui +10
Models of magnetically-driven accretion and outflows reproduce many observational properties of T Tauri stars. This concept is not well established for the more massive Herbig Ae/B…
SU Lyncis, a hard X-ray bright M giant: Clues point to a large hidden population of symbiotic stars
K. Mukai, G. J. M. Luna, G. Cusumano +6
Symbiotic star surveys have traditionally relied almost exclusively on low resolution optical spectroscopy. However, we can obtain a more reliable estimate of their total Galactic…
Discovery of an activity cycle in the solar-analog HD 45184. Exploring Balmer and metallic lines as activity proxy candidates
M. Flores, J. F. González, M. Jaque Arancibia +2
(Abridged) Most stellar activity cycles similar to that found in the Sun have been detected by using the chromospheric Ca II H&K lines as stellar activity proxies. However, it is u…
A temperature condensation trend in the debris-disk binary system Zet2 Ret
C. Saffe, M. Flores, M. Jaque Arancibia +2
We explore condensation temperature Tc trends in the unique binary system Zet1 Ret - Zet2 Ret, to determine whether there is a depletion of refractories, which could be related to…
