Panchromatic Hubble Andromeda Treasury XII. Mapping Stellar Metallicity Distributions in M31
Dylan Gregersen, Anil C. Seth, Benjamin F. Williams +14
We present a study of spatial variations in the metallicity of old red giant branch stars in the Andromeda galaxy. Photometric metallicity estimates are derived by interpolating is…
Constraining Neutrino Cooling using the Hot White Dwarf Luminosity Function in the Globular Cluster 47 Tucanae
Bradley Hansen, Harvey Richer, Jason Kalirai +3
We present Hubble Space Telescope observations of the upper part (T_eff> 10 000 K) of the white dwarf cooling sequence in the globular cluster 47 Tucanae and measure a luminosity f…
Transiting Exoplanet Simulations with the James Webb Space Telescope
Natasha Batalha, Jason Kalirai, Jonathan Lunine +2
In this white paper, we assess the potential for JWST to characterize the atmospheres of super-Earth exoplanets, by simulating a range of transiting spectra with different masses a…
Initial-Final Mass Relation for 3 to 4 M Progenitors of White Dwarfs from the Single Cluster NGC 2099
Jeffrey D. Cummings, Jason S. Kalirai, P. -E. Tremblay +1
We have expanded the sample of observed white dwarfs in the rich open cluster NGC 2099 (M37) with the Keck Low-Resolution Imaging Spectrometer. Of 20 white dwarf candidates, the sp…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
The Panchromatic Hubble Andromeda Treasury XI: The Spatially-Resolved Recent Star Formation History of M31
Alexia R. Lewis, Andrew E. Dolphin, Julianne J. Dalcanton +15
We measure the recent star formation history (SFH) across M31 using optical images taken with the \texit{Hubble Space Telescope} as part of the Panchromatic Hubble Andromeda Treasu…
