Project Hephaistos -- IV. James Webb Space Telescope Observations of Two Dyson Sphere Candidates
Erik Zackrisson, Arjan Bik, Anita Ali Asgar +11
We report on JWST/MIRI imaging and spectroscopy of two M-dwarf stars previously singled out by project Hephaistos as potential Dyson-sphere candidates (their candidates D and E) du…
High-resolution imaging of the radio source associated with Project Hephaistos Dyson Sphere Candidate G
Tongtian Ren, Michael A. Garrett, Andrew P. V. Siemion
We present high-resolution e-MERLIN and EVN (e-VLBI) observations of a radio source associated with Dyson Sphere candidate G, identified as part of Project Hephaistos. The radio so…
Resolved Near-infrared Stellar Photometry from the Magellan Telescope for 13 Nearby Galaxies: JAGB Method Distances
Abigail J. Lee, Andrew J. Monson, Wendy L. Freedman +6
We present near-infrared JHK photometry for the resolved stellar populations in 13 nearby galaxies: NGC 6822, IC 1613, NGC 3109, Sextans B, Sextans A, NGC 300, NGC 55, NGC 7793, NG…
The C/M Ratio of AGB Stars in the Local Group Galaxies
Tongtian Ren, Biwei Jiang, Yi Ren +1
The number ratio of carbon-rich to oxygen-rich asymptotic giant branch (AGB) stars (the so-called C/M ratio) is closely related to the evolution environment of the host galaxy. Thi…
The Sample of Red Supergiants in Twelve Low-Mass Galaxies of the Local Group
Yi Ren, Biwei Jiang, Ming Yang +2
This work establishes the most complete sample of red supergiants (RSGs) in twelve low-mass galaxies (WLM, IC 10, NGC 147, NGC 185, IC 1613, Leo A, Sextans B, Sextans A, NGC 6822,…
