DESCRIPTION:Speakers: Gloria Guilluy (Osservatorio Astrofisico di Torino-I
 NAF)\nHigh-resolution (HR) ground-based spectrographs have drastically imp
 roved the investigation of exoplanet atmospheres. \nWe will present result
 s obtained within the GAPS 2.0 long-term program for atmospheric character
 ization of hot giant planets using the near-infrared 0.95-2.45 \\mu m) arm
  of GIARPS: the high-resolution (R /sim 50 000) spectrograph GIANO-B of th
 e Telescopio Nazionale Galileo (TNG).\nWe will particularly focus on our o
 ngoing efforts to probe exoplanetary atmospheres with the transmission spe
 ctroscopy technique. With the detection of six molecules in the atmosphere
  of the hot-Jupiter HD 209458b (Giacobbe+2021)\, we have demonstrated that
  exoplanetary atmospheres can show a chemical richness previously unknown.
  Here\, we will present the atmospheric characterization of three warm pla
 nets\, namely the super-Neptune WASP-107b (Giacobbe+ in prep.)\, the sub-S
 aturn WASP-69b (Guilluy+2022\, accepted)\, and the sub-Jovian WASP-80b (Ca
 rleo+2022\, accepted).   The simultaneous detection of multiple molecules 
 in their atmospheres reinforces our previous finding revealing a rich atmo
 spheric composition also for warm giant planets. We will give an interpret
 ation of our results in terms of the planet’s C/O ratio and metallicity\
 , which allow us to derive important clues on the formation and migration 
 histories. These analyses represent a new frontier in the characterization
  of exoplanetary atmospheres\, and additional surprising discoveries are e
 xpected in the next future with both ground-based HR spectrographs\, such 
 as CRIRES+\, SPIRou\, and NIRPS\, and the low-resolution (LR) spectrograph
 s on board the JWST telescope.\n\nhttps://meetings.aip.de/event/16/contrib
