No country for old stars -Spectroscopic confirmation of the first intermediate-age RR Lyrae in the open cluster Trumpler 5
Valentina D'Orazi, Cecilia Mateu, Giuliano Iorio +13
RR Lyrae stars are widely considered tracers of ancient (greater than 10 Gyr), metal-poor stellar populations. However, recent kinematic and photometric studies suggest the existen…
LBT Italia: Current Achievements and Future Directions
Silvia Tosi, Ester Marini, Felice Cusano +3
The Large Binocular Telescope (LBT) is a world-leading astronomical observatory, where the italian partnership has played an important role in increasing the telescope's productivi…
Planetary Nebulae of the Large Magellanic Cloud II: the connection with the progenitors' properties
P. Ventura, S. Tosi, D. A. García-Hernández +6
The study of planetary nebulae (PNe) offers the opportunity of evaluating the efficiency of the dust production mechanism during the very late asymptotic giant branch (AGB) phases.…
Planetary Nebulae of the Large Magellanic Cloud I: A multiwavelength analysis
Silvia Tosi, Flavia Dell'Agli, Devika Kamath +5
Planetary nebulae (PNe) have three main components: a central star (CS), ionised gas and dust in the nebula. Each of them contains critical chemical fingerprints of their evolution…
Dust from evolved stars: a pilot analysis of the AGB to PN transition
F. Dell'Agli, S. Tosi, D. Kamath +5
We present a novel approach to address dust production by low- and intermediate-mass stars. We study the asymptotic giant branch (AGB) phase, during which the formation of dust tak…
A study of carbon-rich post-AGB stars in the Milky Way to understand the production of carbonaceous dust from evolved stars
Silvia Tosi, Devika Kamath, Flavia Dell'Agli +5
The goal of this study is to reconstruct the evolution and the dust formation processes during the final AGB phases of a sample of carbon-rich, post-AGB Galactic stars, with partic…
The intense production of silicates during the final AGB phases of intermediate mass stars
E. Marini, F. Dell'Agli, D. Kamath +7
The formation of silicates in circumstellar envelopes of stars evolving through the AGB is still debated given the uncertainties affecting stellar evolution modelling, the descript…
A study of oxygen-rich post-AGB stars in the Milky Way to understand the production of silicates from evolved stars
F. Dell'Agli, S. Tosi, D. Kamath +4
The study of post asymptotic giant branch (post-AGB) stars is a valuable tool to study still poorly known aspects of the evolution of the stars through the AGB. This is due to the…
Understanding dust production and mass loss on the AGB phase using post-AGB stars in the Magellanic Clouds
Silvia Tosi, Flavia Dell'Agli, Devika Kamath +3
Aims: We aim to understand the variation of the surface chemistry that occurs during the AGB phase by analysing results from observations of single post-AGB stars in the Magellanic…
Euclid: Forecasts from the void-lensing cross-correlation
M. Bonici, C. Carbone, S. Davini +129
The Euclid space telescope will survey a large dataset of cosmic voids traced by dense samples of galaxies. In this work we estimate its expected performance when exploiting angula…
New Post-AGB star models as tools to understand AGB evolution and nucleosynthesis
Devika Kamath, Flavia Dell'Agli, Paolo Ventura +3
We study a sample of post-AGB stars in the Galaxy, with known surface chemical composition and s-process enrichment. The recent determination of the luminosities of these sources,…
Multi-filter transit observations of HAT-P-3b and TrES-3b with multiple Northern Hemisphere telescopes
Davide Ricci, Pedro Valdés Sada, Samuel Navarro-Meza +17
We present a photometric follow-up of transiting exoplanets HAT-P-3b and TrES-3b, observed by using several optical and near-infrared filters, with four small-class telescopes (D =…
