The young mini-Neptune HD 207496b that is either a naked core or on the verge of becoming one

S. C. C. Barros, O. D. S. Demangeon, D. J. Armstrong +40

We report the discovery and characterisation of the transiting mini-Neptune HD~207496~b (TOI-1099) as part of a large programme that aims to characterise naked core planets. We obt…

Moonraker -- Enceladus Multiple Flyby Mission

O. Mousis, A. Bouquet, Y. Langevin +50

Enceladus, an icy moon of Saturn, possesses an internal water ocean and jets expelling ocean material into space. Cassini investigations indicated that the subsurface ocean could b…

TOI-969: a late-K dwarf with a hot mini-Neptune in the desert and an eccentric cold Jupiter

J. Lillo-Box, D. Gandolfi, D. J. Armstrong +60

The current architecture of a given multi-planetary system is a key fingerprint of its past formation and dynamical evolution history. Long-term follow-up observations are key to c…

Volatile-rich comets ejected early on during Solar System formation

S. E. Anderson, J. -M. Petit, B. Noyelles +2

Comet C/2016 R2 PanSTARRS (hereafter C/2016 R2) presents an unusually high N2/CO abundance ratio, as well as a heavy depletion in H2O, making it the only known comet of its kind. U…

Constraints on the structure and seasonal variations of Triton's atmosphere from the 5 October 2017 stellar occultation and previous observations

J. Marques Oliveira, B. Sicardy, A. R. Gomes-Júnior +234

A stellar occultation by Neptune's main satellite, Triton, was observed on 5 October 2017 from Europe, North Africa, and the USA. We derived 90 light curves from this event, 42 of…

The SOPHIE search for northern extrasolar planets. XIV. A temperate ( K) super-earth around the nearby star Gliese 411

R. F. Díaz, X. Delfosse, M. J. Hobson +33

Periodic radial velocity variations in the nearby M-dwarf star Gl411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish b…

Different origins or different evolutions? Decoding the spectral diversity among C-type asteroids

P. Vernazza, J. Castillo-Rogez, P. Beck +15

Anhydrous pyroxene-rich interplanetary dust particles (IDPs) have been proposed as surface analogs for about two-thirds of all C-complex asteroids. However, this suggestion appears…
