  12. 4. YO38: validation study for TOI-942
    Ilaria Carleo
    04/05/2020, 15:50

    Here we present a validation study for the TESS object of interest TOI-942. We performed a follow-up of this object with HARPS-N, collecting about 30 spectra. The HARPS-N spectra allow us to characterise the star and confirm the presence of the planet.

    05/05/2020, 11:05

    By performing high-resolution transmission spectroscopy with GIANO-B over the whole near-infrared, we measured the signature of seven molecular species via cross correlation with model spectra.

  20. 21. Disequilibrium chemistry in the atmospheres of the three warm giant planets WASP-69 b, WASP-107b and WASP-80b
    Gloria Guilluy (Istituto Nazionale di Astrofisica (INAF))
    05/05/2020, 11:25

    Here we report preliminary results of the atmospheric studies we performed on the three warm giant planets, Wasp-69b, Wasp-107b and Wasp-80b. By using the PCA technique, and the cross-correlation method, we succeeded in detecting 7 molecules in these exo-atmospheres. Given the low temperature of the investigated exoplanets, some of these molecules are un-expected by equilibrium theories, we...

  21. 22. Modelling exoplanet atmospheres to interpret GIANO observations
    Matteo Brogi (University of Warwick)
    05/05/2020, 14:30

    Near-infrared high-resolution spectroscopy relies on cross correlation with model spectra to extract information about the chemical and physical conditions of exoplanet atmospheres. In this talk I will review recent efforts to identify the most reliable molecular line lists applicable to simulate the high temperatures of extrasolar planets. Furthermore, I will explain how GIANO could be used...

  22. 3. Understanding the XUV-induced Atmospheric Erosion of Young Planets and their Evolution With Time
    Darius Modirrousta Galian (Istituto Nazionale di Astrofisica (INAF))
    05/05/2020, 14:50

    In the talk we will discuss the effects of X-ray and ultraviolet radiation on atmospheric erosion around young stars. Specifically, we focus on the bimodal distribution of exoplanet radii (i.e. “The Fulton Gap”; Fulton et al. 2017). In Modirrousta-Galian et al. (2020,b) this distribution is theoretically analysed in order to make several predictions that can be astronomically tested. For...

    The knowledge of planetary mass and radius of young planets is crucial in the understanding if their atmospheres can survive at the intense XUV stellar irradiation

  32. 23. Atmospheric parameters and chemical composition of YO stars
    Martina Baratella (Università degli studi di Padova)
    06/05/2020, 14:30

    The detailed characterisation of stars is important in many astrophysical fields. In particular, knowing with great precision the atmospheric parameters and chemical composition of planet hosting stars allows to fully characterise exoplanets and address a number of aspects, e.g. the planet-metallicity relation.
    In our work, we performed a precise determination of the atmospheric parameters...

  33. 2. The abundance signature of low-mass stars with planets.
    Jesus Maldonado Prado (Istituto Nazionale di Astrofisica (INAF))
    06/05/2020, 14:50

    Methods to derive in a consistent way stellar abundances of low-mass stars from optical spectra are still missing. In this contribution we present a first attempt to fill this gap. Our methodology is based on the use of principal componen analysis and sparse Bayesian’s fitting methods. A set of M dwarfs in binary systems orbiting around an FGK primary was observed and is used to training our...

  36. 41. Correcting the impact of stellar spots on ARIEL transmission spectra
    Giancluca Cracchiolo
    06/05/2020, 15:50

    In my study, I analyze the impact of stellar spots on ARIEL observations and their effects on the extraction of the planetary signal from primary transit observations. I develop a method to determine the size and temperature of the spots by using the out-of-transit observations and I define a procedure to reliably extract the planetary spectrum in the presence of spots.
