The HARPS search for southern extra-solar planets. XXXIX. HD175607 b, the most metal-poor G dwarf with an orbiting sub-Neptune
A. Mortier, J. P. Faria, N. C. Santos +16
Context. The presence of a small-mass planet (M0.1\,M) seems, to date, not to depend on metallicity, however, theoretical simulations have shown that stars with subsol…

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…

Evidence for a spectroscopic direct detection of reflected light from 51 Peg b
J. H. C. Martins, N. C. Santos, P. Figueira +11
The detection of reflected light from an exoplanet is a difficult technical challenge at optical wavelengths. Even though this signal is expected to replicate the stellar signal, n…
