The distance of M33 and the stellar population in its outskirts

, 2004
We present deep V,I photometry of two $9.4' x 9.4' field in the outer regions of the M33 galaxy. We obtain a robust detection of the luminosity of the Red Giant Branch Tip (I{TRGB}=20.72 +- 0.08) from which we derived a new estimate of the distance ...

FEAST: Probing the Stellar Population of the Starburst Dwarf Galaxy NGC 4449 with JWST/NIRCam

The Astrophysical Journal
We present new JWST/NIRCam observations of the starburst irregular galaxy NGC 4449, obtained in Cycle 1 as part of the Feedback in Emerging extrAgalactic Star clusTers program, which we use to investigate its resolved stellar populations and their ...

Sodium production in asymptotic giant branch stars

, 1999
[condensed] A new scenario is presented for the production of Na23 in asymptotic giant branch (AGB) stars. The scenario takes advantage of the periodic third dredge-up episodes characterizing those stars, which mix primary C12 from their intershell layers to their surface. Two successive interpulse/pulse/dredge-up sequences are then required to produce

Observations of Molecular CN toward S-type Asymptotic Giant Branch Stars

The Astronomical Journal
S-type asymptotic giant branch (AGB) stars are defined by their carbon-to-oxygen (C/O) ratio approaching unity. However, observations of circumstellar molecules in these stars are limited and challenging.
