Three-dimensional Orbit and Dynamical Masses of GJ 105 AC
Cayla M. Dedrick, Jason T. Wright, Jason D. Eastman +11
The precision of stellar models is higher than the precision at which we are able to measure the masses of most stars, with the notable exception of binaries where we can determine…
TOI-1994b: A Low Mass Eccentric Brown Dwarf Transiting A Subgiant Star
Emma Page, Joshua Pepper, Duncan Wright +22
We present the discovery of TOI-1994b, a low-mass brown dwarf transiting a hot subgiant star on a moderately eccentric orbit. TOI-1994 has an effective temperature of $7700^{+720}_…
The GALAH survey: effective temperature calibration from the InfraRed Flux Method in the Gaia system
L. Casagrande, J. Lin, A. D. Rains +23
In order to accurately determine stellar properties, knowledge of the effective temperature of stars is vital. We implement Gaia and 2MASS photometry in the InfraRed Flux Method an…
The GALAH Survey: A new constraint on cosmological lithium and Galactic lithium evolution from warm dwarf stars
Xudong Gao, Karin Lind, Anish M. Amarsi +22
Lithium depletion and enrichment in the cosmos is not yet well understood. To help tighten constraints on stellar and Galactic evolution models, we present the largest high-resolut…
The GALAH survey: Characterization of emission-line stars with spectral modelling using autoencoders
Klemen Čotar, Tomaž Zwitter, Gregor Traven +11
We present a neural network autoencoder structure that is able to extract essential latent spectral features from observed spectra and then reconstruct a spectrum from those featur…
The GALAH survey: A census of lithium-rich giant stars
Sarah Martell, Jeffrey Simpson, Adithya Balasubramaniam +20
We investigate the properties of 1262 red giant stars with high photospheric abundances of lithium observed by the GALAH and \Ktwo-HERMES surveys, and discuss them in the context o…
