Hydrodynamical interaction of stellar and planetary winds: effects of charge exchange and radiation pressure on the observed Ly absorption
A. Esquivel, M. Schneiter, C. Villarreal D'Angelo +2
Lyman observations of the transiting exoplanet HD 209458b enable the study of exoplanets exospheres exposed to stellar EUV fluxes, as well as the interacting stellar wind prope…
TOROS Optical follow-up of the Advanced LIGO-VIRGO O2 second observational campaign
Rodolfo Artola, Martin Beroiz, Juan Cabral +48
We present the results of the optical follow-up, conducted by the TOROS collaboration, of gravitational wave events detected during the Advanced LIGO-Virgo second observing run (No…
Machine Learning on Difference Image Analysis: A comparison of methods for transient detection
B. Sánchez, M. J. Domínguez R., M. Lares +12
We present a comparison of several Difference Image Analysis (DIA) techniques, in combination with Machine Learning (ML) algorithms, applied to the identification of optical transi…
Slow magnetoacoustic gravity waves in an equilibrium stratified solar atmosphere: cut-off periods through the transition region
A. Costa, M. Schneiter, E. Zurbriggen
Assuming the thin flux tube approximation, we introduce an analytical model that contemplates the presence of: a non-isothermal temperature; a varying magnetic field and a non-unif…
Magnetised winds and their influence in the escaping upper atmosphere of HD 209458b
Carolina Villarreal D'Angelo, Alejandro Esquivel, Matías Schneiter +1
Lyman observations during an exoplanet transit have proved to be very useful to study the interaction between the stellar wind and the planetary atmosphere. They have been exte…
Observations of the first electromagnetic counterpart to a gravitational wave source by the TOROS collaboration
M. C. Díaz, L. M. Macri, D. Garcia Lambas +52
We present the results of prompt optical follow-up of the electromagnetic counterpart of the gravitational-wave event GW170817 by the Transient Optical Robotic Observatory of the S…
MHD simulations of coronal supra-arcade downflows including anisotropic thermal conduction
E. Zurbriggen, A. Costa, A. Esquivel +2
Coronal supra-arcade downflows (SADs) are observed as dark trails descending towards hot turbulent fan shaped regions. Due to the large temperature values, and gradients in these f…
GW150914: First search for the electromagnetic counterpart of a gravitational-wave event by the TOROS collaboration
Mario C. Díaz, Martín Beroiz, Tania Peñuela +31
We present the results of the optical follow-up conducted by the TOROS collaboration of the first gravitational-wave event GW150914. We conducted unfiltered CCD observations (0.35-…
Two step chromospheric Moreton wave excitation in a blast-wave scenario. A case study: the December 06, 2006 event
G. Krause, M. Cécere, C. Francile +3
We examine the capability of a blast-wave scenario -associated to a coronal flare or to the expansion of CME flanks- to reproduce a chromospheric Moreton phenomenon. We also simula…
Benchmarking the power of amateur observatories for TTV exoplanets detection
Roman V. Baluev, Evgenii N. Sokov, Vakhit Sh. Shaidulin +13
We perform an analysis of ~80000 photometric measurements for the following 10 stars hosting transiting planets: WASP-2, -4, -5, -52, Kelt-1, CoRoT-2, XO-2, TrES-1, HD 189733, GJ 4…
3D MHD simulation of flare supra-arcade downflows in a turbulent current sheet medium
M. Cécere, E. Zurbriggen, A. Costa +1
Supra-arcade downflows (SADs) are sunward, generally dark, plasma density depletions originated above posteruption flare arcades. In this paper using 3D MHD simulations we investig…
Simulation of descending multiple supra--arcade reconnection outflows in solar flares
M. Cécere, M. Schneiter, A. Costa +2
After recent AIA observations by Savage, McKenzie and Reeves we revisit the scenario proposed by us in previous papers. We have shown that sunward, generally dark plasma features o…
