Radial velocity information content of M dwarf spectra in the near-infrared
P. Figueira, V. Zh. Adibekyan, M. Oshagh +7
Aims: We evaluate the radial velocity (RV) information content and achievable precision on M0-M9 spectra covering the ZYJHK bands. We do so while considering both a perfect atmosph…
Polar stellar-spots and grazing planetary transits: possible explanation for the low number of discovered grazing planets
M. Oshagh, N. C. Santos, P. Figueira +4
We assess a physically feasible explanation for the low number of discovered (near-)grazing planetary transits through all ground and space based transit surveys. We performed simu…
Identifying the best iron-peak and -capture elements for chemical tagging: The impact of the number of lines on measured scatter
V. Adibekyan, P. Figueira, N. C. Santos +9
The main goal of this work is to explore which elements carry the most information about the birth origin of stars and as such that are best suited for chemical tagging. We explore…
Detecting ring systems around exoplanets using high resolution spectroscopy: the case of 51Pegb
N. C. Santos, J. H. C. Martins, G. Boué +13
In this paper we explore the possibility that the recently detected reflected light signal of 51\,Peg\,b could be caused by a ring system around the planet. We use a simple model t…
