Planets and X-rays: a radiation diet
J. Sanz-Forcada, I. Ribas, G. Micela +4
According to theory, high energy emission from the coronae of cool stars can severely erode the atmosphere of orbiting planets. To test the long term effects of the erosion we stud…
Starspots on the fastest rotators in the Beta Pic moving group
D. Garcia-Alvarez, A. F. Lanza, S. Messina +7
Aims: We carried out high-resolution spectroscopy and BV(I)_C photometric monitoring of the two fastest late-type rotators in the nearby Beta Pictoris moving group, HD199143 (F7V)…
Multi-Wavelength Study of the 2008-2009 Outburst of V1647 Ori
D. Garcia-Alvarez, N. J. Wright, J. J. Drake +11
V1647 Ori is a young eruptive variable star, illuminating a reflection nebula (McNeil's Nebula). It underwent an outburst in 2003 before fading back to its pre-outburst brightness…
Estimation of the XUV radiation onto close planets and their evaporation
J. Sanz-Forcada, G. Micela, I. Ribas +5
Context: The current distribution of planet mass vs. incident stellar X-ray flux supports the idea that photoevaporation of the atmosphere may take place in close-in planets. Integ…
A comparison of a few numerical schemes for the integration of stochastic differential equations in the Stratonovich interpretation
David Garcia-Alvarez
Three schemes, whose expressions are not too complex, are selected for the numerical integration of a system of stochastic differential equations in the Stratonovich interpretation…
