The Milky Way Bulge Extra-Tidal Star Survey: NGC 6569

Joanne Hughes, Andrea Kunder, Kevin Covey +25

We present spectroscopic evidence for tidal debris associated with the bulge globular cluster NGC 6569, based on medium-resolution (R ~ 11,000) Anglo-Australian Telescope spectra o…

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 […

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 ($…

A theoretical framework for BL Her stars III. A case study: Robust light curve optimisation in the LMC

Susmita Das, László Molnár, Gábor B. Kovács +8

We carry out an extensive light curve comparison of BL Her stars using observations from Gaia DR3 and stellar pulsation models computed using MESA-RSP with the goal to obtain the b…
