Physical parameters and long-term photometric variability of V1481 Ori, a SB2 member of Orion Nebula Cluster with an accreting component

Sergio Messina, Padmakar Parihar, Katia Biazzo +5

We present the results of our analysis on V1481 Ori (JW 239), a young SB2 in the Orion Nebula Cluster with a circumbinary disc accreting on the lower-mass component. The analysis i…

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…

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…

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…

WISE J061213.85-303612.5: a new T-dwarf binary candidate

N. Huélamo, V. D. Ivanov, R. Kurtev +8

T and Y-dwarfs are among the coolest and least luminous objects detected, and they can help to understand the properties of giant planets. Their multiplicity properties can shed li…

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…
