1. Planetary characterisation to support Ariel target selection

Dr Serena Benatti (Istituto Nazionale di Astrofisica (INAF))

06/05/2026, 16:30

In this talk, I will present a summary of the observational efforts to characterise the planets that could be observed by Ariel and how these studies can support the selection of the future Ariel targets.
In particular, I will present the "Ariel Masses Survey (ArMS)" with the HARPS-N spectrograph at the Telescopio Nazionale Galileo, which is a five-year large program dedicated to the radial...

3. Validation of Ariel candidates orbiting M-K stars

One of the key goals in planetary population studies is to achieve broad coverage of the parameter space, which is not fully covered by the currently confirmed planets. We can fulfil this aim by incorporating validated planets even if they have not been confirmed yet. Therefore, we can validate them through a vetting procedure. Within the Ariel Mission Candidates Sample, the TESS Planet...

6. The Ariel Planetary Catalogue: An homogenous statistically derived catalogue of exoplanetary parameters

Mattia Claudio D'Arpa (Istituto Nazionale di Astrofisica (INAF))

06/05/2026, 17:15

We present a new, self-consistent catalog of planetary parameters derived from the ARIEL Stellar Catalogue (ASC), a homogeneous dataset of stellar properties. Our work leverages this robust reference frame to provide accurate planetary characteristics for systems in the ARIEL Mission Candidate Sample. We compare our newly derived planetary parameters with those available in the...

22. MINERVA: Minimum observations for accurate Exoplanetary mass estimation with Radial Velocity Analysis — A New Tool for Estimating the Observational Effort in Exoplanetary Mass Determination

Dr Claudia Di Maio (Istituto Nazionale di Astrofisica (INAF))

06/05/2026, 17:35

Precise planetary mass measurements are essential for constraining the internal structure and atmospheric properties of exoplanets. In the framework of the ESA Ariel mission, accurate masses are required to break key degeneracies in atmospheric retrievals. Estimating the observational effort needed to reach the desired mass precision is therefore crucial for the optimisation of current and...
