Revisiting the correlation between stellar activity and planetary surface gravity
P. Figueira, M. Oshagh, V. Zh. Adibekyan +1
Aims: We re-evaluate the correlation between planetary surface gravity and stellar host activity as measured by the index log(). This correlation, previously identified by…
Improvements on analytic modelling of stellar spots
M. Montalto, G. Boué, M. Oshagh +3
In this work we present the solution of the stellar spot problem using the Kelvin-Stokes theorem. Our result is applicable for any given location and dimension of the spots on the…
Impact of occultations of stellar active regions on transmission spectra: Can occultation of a plage mimic the signature of a blue sky?
M. Oshagh, N. C. Santos, D. Ehrenreich +4
Transmission spectroscopy during planetary transits, which is based on the measurements of the variations of planet-to-star radius ratio as a function of wavelength, is a powerful…
The HARPS search for southern extra-solar planets XXXV. The interesting case of HD41248: stellar activity, no planets?
N. C. Santos, A. Mortier, J. P. Faria +21
The search for planets orbiting metal-poor stars is of uttermost importance for our understanding of the planet formation models. However, no dedicated searches have been conducted…
