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…
Precision constraints on stellar physics from main sequence detached eclipsing binaries
Mitchell T. Dennis, Harry Desmond, Jeremy Sakstein
We present a Bayesian framework to constrain {mass (), metallicity (), stellar age (), and the convective mixing length parameter ()} in main-sequence (MS)…
Impact of Simultaneous Stellar Modeling Uncertainties on the Tip of the Red Giant Branch for Axion-Election Coupling
Mitchell T. Dennis, Jeremy Sakstein
We present a novel method for incorporating the effects of stellar modeling uncertainties into constraints on the axion-electron coupling constant found using the observed calibrat…
Machine Learning the Tip of the Red Giant Branch
Mitchell Dennis, Jeremy Sakstein
A method for investigating the sensitivity of the tip of the red giant branch (TRGB) I band magnitude to stellar input physics is presented.~We compute a grid of 125,00…
Identifying catastrophic outlier photometric redshift estimates in the COSMOS field with machine learning methods
Mitchell T. Dennis, Esther M. Hu, Lennox L. Cowie
We present the result of two binary classifier ensembled neural networks to identify catastrophic outliers for photo-z estimates within the COSMOS field utilizing only 8 and 5 phot…
