Stranger Things: A Grid-based Survey of Strange Modes in Post-Main Sequence Models
D. Tarczay-Nehéz, L. Molnár, M. Joyce
We present a systematic survey of strange mode pulsations in Cepheids using MESA and for the linear stability analysis, MESA RSP. Our model grid spans in mass and […
Benchmarking differential reddening in front of globular clusters
Csilla Kalup, László Molnár
Interstellar extinction is a major obstacle in determining accurate stellar parameters from photometry near the Galactic disk. It is especially true for globular clusters at low ga…
Empirical Globular Cluster Ridgeline Construction on Gaia Data
Anett Simon-Zsók, László Molnár, Csilla Kalup +1
We present a new method and a corresponding code to compress the color magnitude diagram of a globular cluster into a representative curve, called a ridgeline, that can be more rea…
Betelgeuse's Buddy: X-Ray Constraints on the Nature of Ori B
Anna J. G. O'Grady, Brendan O'Connor, Jared A. Goldberg +8
The d Long Secondary Period of Betelgeuse's optical lightcurve and radial velocity motivated the prediction of a low-mass stellar companion, expected to be at maximal a…
Betelgeuse, Betelgeuse, Betelgeuse, Betel-buddy? Constraints on the dynamical companion to Orionis from HST
Jared A. Goldberg, Anna J. G. O'Grady, Meridith Joyce +10
Recently, two independent analyses have asserted that the cause of the Long Secondary Period (LSP) observed in the variability spectrum of our nearest red supergiant, Betelgeuse ($…
