Confirmation of the hot super-Neptune TOI-672 b with NIRPS and HARPS and Insights into the Neptunian desert around M dwarfs

Ares Osborn, Ryan Cloutier, Vincent Bourrier +65

The Neptunian desert is a distinct lack of Neptune-sized planets at short orbital periods, purportedly carved by photoevaporation and tidal circularization following high-eccentric…

Evidence of a substellar companion around a very young T Tauri star

P. Viana Almeida, J. F. Gameiro, P. P. Petrov +4

We present results from a Near Infrared multi-epoch spectroscopic campaign to detect a young low-mass companion to a T Tauri star. AS 205A is a late-type dwarf (~K5) of ~1 Msun tha…

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems

P. Bluhm, M. I. Jones, L. Vanzi +10

We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orb…

Reflected light from giant planets in habitable zones: Tapping into the power of the Cross-Correlation Function

Jorge H. C. Martins, Nuno C. Santos, Pedro Figueira +1

The direct detection of reflected light from exoplanets is an excellent probe for the characterization of their atmospheres. The greatest challenge for this task is the low planet-…

An extensive radial velocity survey toward NGC 6253

M. Montalto, C. H. F. Melo, N. C. Santos +6

The old and metal rich open cluster NGC 6253 was observed with the FLAMES multi-object spectrograph during an extensive radial velocity campaign monitoring 317 stars with a median…

Giant planets around two intermediate-mass evolved stars and confirmation of the planetary nature of HIP67851 c

M. I. Jones, J. S. Jenkins, P. Rojo +1

Precision radial velocities are required to discover and characterize planets orbiting nearby stars. Optical and near infrared spectra that exhibit many hundreds of absorption line…
