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…

Impact of micro-telluric lines on precise radial velocities and its correction

D. Cunha, N. C. Santos, P. Figueira +3

Context: In the near future, new instruments such as ESPRESSO will arrive, allowing us to reach a precision in radial-velocity measurements on the order of 10 cm/s. At this level o…

Spin evolution of Earth-sized exoplanets, including atmospheric tides and core-mantle friction

Diana Cunha, Alexandre C. M. Correia, Jacques Laskar

Planets with masses between 0.1 - 10 M_earth are believed to host dense atmospheres. These atmospheres can play an important role on the planet's spin evolution, since thermal atmo…

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…

Impact of stellar companions on precise radial velocities

D. Cunha, P. Figueira, N. C. Santos +2

Context: With the announced arrival of instruments such as ESPRESSO one can expect that several systematic noise sources on the measurement of precise radial velocity will become t…
