Disco in the Dust: Reflected light at the bow shock around Betelgeuse's companion explains its observed luminosity
Jared A. Goldberg, Meridith Joyce, Anna J. G. O'Grady +6
Recent detections of Orionis B, the putative companion to Betelgeuse, have been reported using multiple instruments and techniques. These include, most recently, a detect…
Custom Colors: A Module for Computing Synthetic Photometry On-the-Fly in Stellar Evolution Calculations, Integrated with MESA and Usable with Other Stellar Evolution Codes
Niall Miller, Meridith Joyce, Philip Mocz
Stellar evolution simulations predict physical quantities such as luminosity, whereas broadband photometric observations measure flux in specific bandpasses; converting the predict…
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 […
The Two-infall Model Revisited: Constraints on Milky Way Bulge Assembly from >30,000 Galactic Chemical Evolution Models and Machine Learning
Niall Miller, Meridith Joyce, Christian I. Johnson +3
We constrain the formation history of the Milky Way bulge using a two-infall galactic chemical evolution (GCE) algorithm implemented in the N'OMEGA+ code. We recover a best-fit sce…
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…
Matching seismic masses for RR Lyrae-type and oscillating red horizontal-branch stars in M4
László Molnár, Henryka Netzel, Madeline Howell +2
Globular clusters offer a powerful way to test the properties of stellar populations and the late stages of low-mass stellar evolution. In this paper we study oscillating giant sta…
A Buddy for Betelgeuse: Binarity as the Origin of the Long Secondary Period in Orionis
Jared A. Goldberg, Meridith Joyce, László Molnár
We predict the existence of Ori B, a low-mass companion orbiting Betelgeuse. This is motivated by the presence of a 2170-day Long Secondary Period (LSP) in Betelgeuse's lightcu…
RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99
Evan Butler, Andrea Kunder, Zdenek Prudil +16
Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…
The Milky Way Bulge extra-tidal star survey: BH 261 (AL 3)
Andrea Kunder, Zdenek Prudil, Kevin Covey +19
The Milky Way Bulge extra-tidal star survey (MWBest) is a spectroscopic survey with the goal of identifying stripped globular cluster stars from inner Galaxy clusters. In this way,…
The Blanco DECam Bulge Survey (BDBS) VIII: Chemo-kinematics in the southern Galactic bulge from 2.3 million red clump stars with Gaia DR3 proper motions
Tommaso Marchetti, Meridith Joyce, Christian Johnson +5
The Blanco DECam Bulge Survey (BDBS) provides near-ultraviolet to near-infrared photometry for ~250 million unique stars. By combining BDBS photometry with the latest Gaia astromet…
