چکیده

In this study we present a data set of synthetic photometry of M-type AGB stars for JWST, WISE and a lter set that will be referred to as the generic lter set, consisting of: UX BX B V R I J J2m H H2m Ks2m K L L’ M M’. 106 di erent models compromised of 4741 spectra have been processed for the three lter sets. We have also tted the models to eight observations of M-type AGB stars made by WISE, showing that the models fairly well can recreate observations but that there is de nitely still room for improvements. The resulting photometric les can be accessed at http://www.astro.uu.se/AGBmodels/ABmags/.

Prospects for Studies of Stellar Evolution and Stellar Death in the JWST Era

I review the prospects for studies of the advanced evolutionary stages of low-, intermediateand high-mass stars by the JWST and concurrent facilities, with particular emphasis on how they may help elucidate the dominant contributors to the interstellar dust component of galaxies. Observations extending from the mid-infrared to the submillimeter can help quantify the heavy element and dust speci...

A Spitzer Irac Census of the Asymptotic Giant Branch Populations in Local Group Dwarfs. Ii. Ic 1613

We present Spitzer Space Telescope IRAC photometry of the Local Group dwarf irregular galaxy IC 1613. We compare our 3.6, 4.5, 5.8, and 8.0 μm photometry with broadband optical photometry and find that the optical data do not detect 43% and misidentify an additional 11% of the total AGB population, likely because of extinction caused by circumstellar material. Further, we find that a narrowband...

Pulsating red giant and supergiant stars in the Local Group dwarf galaxy Andromeda I

We have conducted an optical long-term monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify the long period variable (LPV) stars. LPV stars vary on timescales of months to years, and reach the largest amplitudes of their brightness variations at optical wavelengths, due to the changing temperature. They trace stellar populati...

Near-infrared photometry and optical spectroscopy of IRAS sources in the Small Magellanic Cloud

Near-infrared photometry is obtained of 30 IRAS sources in the direction of the Small Magellanic Cloud selected to be possible AGB stars. Low resolution 4000 to 10 000 Å spectroscopy is presented for 10 of them, plus two AGB stars in the LMC. Improved IRAS fluxes are obtained using the gipsy package. Based on the optical spectra and analyses of colour-colour diagrams 9 are confirmed or likely c...

PG 1323 − 086 and PG 1704 + 222 – two post - AGB stars at high galactic latitudes

Two high galactic latitude B-type stars, PG 1323−086 and PG 1704+222, are analysed from low and medium resolution optical spectra and Strömgren photometry. A differential abundance analysis for He, C, N, O, Mg, Al, and Si reveals that the He abundance is close to solar while metal underabundances relative to the solar value of typically 1.3 and 1.2 dex for PG 1323−086 and PG 1704+222, respectiv...
