Titolo: Tirocini e tecnologie emergenti: lune nel metaverso e stelle in realtà aumentata

Abstract:
Dal 2020, l’Osservatorio Astronomico di Palermo (OAPA) promuove tirocini accademici rivolti a studenti e studentesse delle lauree triennali e magistrali in Fisica e Ingegneria, offrendo l’opportunità, attualmente unica in INAF, di approfondire la comunicazione e la didattica dell’astronomia attraverso l’uso di tecnologie innovative come la realtà aumentata (AR) e la realtà virtuale (VR). Durante l’incontro verranno presentati i progetti sviluppati dalle tirocinanti: un tour immersivo nel metaverso dedicato all’esplorazione delle lune del sistema solare e un’esperienza in realtà aumentata che racconta, in modo visivo e interattivo, il ciclo di vita delle stelle. Ci sarà l’opportunità di interagire con i progetti utilizzando visori VR e tablet, per un viaggio nell’universo che combina scienza, tecnologia, ricerca e curiosità.

Titolo: “Retrieving the Atmospheres of Distant Worlds: Insights from High-Resolution Spectroscopy”

Abstract: “High-resolution (HR) transmission spectroscopy has demonstrated exceptional effectiveness in detecting multiple molecular species in the atmospheres of exoplanets. At HR, molecular absorption bands are resolved into thousands of individual spectral lines, allowing for unambiguous identification of species through line matching (e.g., via cross-correlation) with planetary model templates, even when most individual lines are buried within photon noise. The next frontier is to connect the detection of molecular species to the underlying chemical and physical properties of exoplanetary atmospheres. We discuss the prospects of this technique in the context of upcoming facilities, such as the Extremely Large Telescope (ELT), highlighting its potential to revolutionize our understanding of exoplanet atmospheres.”

Titolo: INVESTIGATING EXOPLANETARY ATMOSPHERES THROUGH TRANSMISSION SPECTROSCOPY

Abstract:

The thesis is focused on the search and characterisation of atmospheric signals from the exoplanet atmosphere, the transmission spectrum, using both high- and low-resolution transmission spectroscopy observations of several exoplanets. The majority of the research presented in this thesis pertains to applying the method developed for deriving the transmission spectrum of individual lines while thoroughly removing Earth and stellar contaminants. I will discuss various studies focusing on KELT-9 b, the most scorching exoplanet discovered. Furthermore, I will demonstrate how this method, initially devised for KELT-9 b, can be applied to other subjects, including several hot Jupiters. A notable application of the framework developed for single line analysis is using both the Halpha line and the He I triplet as markers of two distinct star-planet interactions: stellar activity and photo-evaporation. Regarding the low-resolution spectroscopy I will introduce the preliminary results of one ongoing project regarding the comparison between different pipelines used to extract the transmission spectra from HST WFC3 data. I will show how slightly different results obtained by these pipelines would lead to differences in the chemical composition retrieved.
