Population demographics of post-interaction WDMS binaries: From common envelope evolution to stable mass transfer
Natsuko Yamaguchi, Kareem El-Badry, Cheyanne Shariat
The authors jointly model three observational samples of white‑dwarf + main‑sequence binaries to constrain how mass transfer and common‑envelope phases shape their demographics, fi…
How precisely can we measure the ages of subgiant and giant stars?
Cheyanne Shariat, Kareem El-Badry, Soumyadeep Bhattacharjee
Precise stellar ages are fundamental to Galactic archaeology. However, obtaining reliable age estimates and uncertainties for field stars has been a long-standing challenge. We tes…
Probing the IMF in the Early Universe -- Direct measurements in the Boötes I UFD with JWST/NIRCam
Keyi Ding, Mario Gennaro, Roberto J. Avila +20
The dependence of the stellar initial mass function (IMF) on star-formation environment, particularly at low metallicities and high redshifts, remains poorly constrained. Ultra-fai…
OverCite: Add citations in LaTeX without leaving the editor
Cheyanne Shariat
Adding citations while drafting in LaTeX often requires leaving the editor, searching for a paper in mind, copying its BibTeX entry into the project bibliography, renaming the cite…
Gaia astrometry disfavors a binary origin for long secondary periods
Cheyanne Shariat, Kareem El-Badry, Morgan MacLeod +1
Approximately one-third of luminous pulsating red giant stars exhibit long secondary periods (LSPs): stable photometric variability with periods of several months to years in addit…
Thermally inflated accretors in post-mass transfer binaries: Abell 35 and its class revisited
Soumyadeep Bhattacharjee, Kareem El-Badry, Jim Fuller +2
A small but growing class of binaries containing hot () white dwarfs (WDs) and rapidly rotating, apparently subgiant companions -- including the proto…
