Dust in the very metal-poor galaxy Sextans A with JWST. I: Characterizing the evolved stellar population of Sextans A based on JWST observations and stellar evolution models
C. Gavetti, F. Dell'Agli, E. Tarantino +22
The nearby star-forming dwarf galaxy Sextans A offers a unique window into galaxy evolution in the early Universe, owing to its extremely low metallicity (about 1-7% Zsun). Recent…
The applicability of the JAGB method for measuring the distance of galaxies subject to different metal enrichment rates
Claudio Gavetti, Paolo Ventura, Flavia Dell'Agli +4
The JAGB method has been proposed in recent years as a possible distance indicator for galaxies in the Local Group and beyond. However, the nature of the stars populating the J reg…
An analysis of the J-method from the perspective of the AGB evolution
C. Gavetti, P. Ventura, F. Dell'Agli +2
The JAGB method has been proposed as a distance indicator for Local Group galaxies. We investigate the populations of the J region in the (J-K,J) colour-magnitude plane of the Larg…
A study of Andromeda to improve our knowledge on the evolution and dust production by AGB stars
Claudio Gavetti, Paolo Ventura, Flavia Dell'Agli +4
We study the AGB population of the galaxy M31, based on available HST and Spitzer data, to characterize the individual sources in terms of mass, metallicity and formation epoch of…
