SUMMARY:colloquium Paolo Saracco - SHARP - A Near-IR Multi-mode Spectrograph conceived for the Multi-Conjugate adaptive optics module MORFEO@ELT
DESCRIPTION:The world’s largest aperture combined with state-of-the-art Adaptive Optics systems will enable the ELT to capture better data than the JWST in both sharpness and depth. Therefore\, the spectrograph intended for the 2nd port of the Multi-Conjugate Adaptive Optics (MCAO) system MORFEO@ELT will be the most powerful instrument of the JWST era\, revealing phenomena beyond the reach of others. SHARP (http://sharp.brera.inaf.it) is a near-IR (0.95-2.45 mu) spectrograph designed for the 2nd port of MORFEO@ELT\, intended to be submitted in the upcoming ESO instrument call. Comprising a Multi-Object Spectrograph\, NEXUS\, and a multi-Integral Field Unit\, VESPER\, SHARP extends its wavelength range to ~2.45 μ. Coupled with MCAO-assisted observations\, it delivers unprecedented high angular (~30 mas) and spectral resolution\, outperforming NIRSpec@JWST (100 mas). MORFEO-SHARP will allow us to study the nearby and the early Universe in unprecedented detail\, resolving the first galaxies and the star forming regions within galaxies far back in cosmic time\, and providing spectra of individual nearby young stellar objects. This presentation introduces the scientific rationale behind SHARP\, showcasing its features and inviting those interested to join the SHARP team.

SUMMARY:Colloquium Letizia Stanghellini - Advances in stellar and galactic evolution with the population of planetary nebula progenitors from the APOGEE DR17 survey
DESCRIPTION:Planetary nebulae (PNe) are the ejected gas and dust shells of Asymptotic Giant Branch (AGB) stars\, which represent the late life of low- and intermediate-mass stars (LIMS). With the advent of the APOGEE DR17 survey\, there is a purpose in comparing Red Giants (RGs) and PNe abundances to disclose their similarities and differences since such a comparison has been rarely\, and not recently\, done in the Milky Way. While we expect similarities in most of the alpha-element distributions across the two populations\, given their limited evolution in LIMS\, differences in Fe and S abundances allow us to determine their depletion due to grain condensation in post-AGB phases. Differences in N and C between PNe and their progenitors set new limits to their production in the late stages of LIMS evolution. Finally\, we use radial metallicity gradients from RGs and PNe and Gaia-calibrated distances to constrain galaxy evolution in the framework of the current chemical evolution models.
