The Case for High-Resolution Infrared Spectroscopy with the Habitable Worlds Observatory
Daniel Jaffe, Gregory Mace, Erica Sawczynec +2
A high-resolution near-IR spectroscopy capability on the Habitable Worlds Observatory (HWO) could strongly and efficiently advance many of the mission's goals. The technical barrie…
Rubidium Abundances in Cool Giants from High-Resolution H-band Spectra: A New Diagnostic for Galactic Chemical Evolution
Nils Ryde, Jess Kocher, Govind Nandakumar +6
The Galactic Center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near…
10 Years of Archival High-Resolution NIR Spectra: The Raw and Reduced IGRINS Spectral Archive (RRISA)
Erica Sawczynec, Kyle F. Kaplan, Gregory N. Mace +20
The Immersion GRating INfrared Spectrometer (IGRINS) is a compact, high-resolution (R~45,000) near-infrared spectrograph spanning 1.45 to 2.45 um in a single exposure. We introduce…
A giant planet transiting a 3-Myr protostar with a misaligned disk
Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg +35
Astronomers have found more than a dozen planets transiting 10-40 million year old stars, but even younger transiting planets have remained elusive. A possible reason for the lack…
Chemical Links between a Young M-type T Tauri Star and its Substellar Companion: Spectral Analysis and C/O Measurement of DH Tau A
Neda Hejazi, Jerry W. Xuan, David R. Coria +5
The chemical abundance measurements of host stars and their substellar companions provide a powerful tool to trace the formation mechanism of the planetary systems. We present a de…
A New Asteroseismic Benchmark Constrains the Onset of Weakened Magnetic Braking in Mature Sun-Like Stars
Vanshree Bhalotia, Daniel Huber, Jennifer L. van Saders +11
Stellar spin down is a critical yet poorly understood component of stellar evolution. In particular, results from the Kepler Mission imply that mature age, solar-type stars have in…
The IGRINS YSO Survey III: Stellar parameters of pre-main sequence stars in Ophiuchus and Upper Scorpius
Ricardo López-Valdivia, Gregory N. Mace, Eunkyu Han +9
We used the Immersion GRating Infrared Spectrometer (IGRINS) to determine fundamental parameters for 61 K- and M-type young stellar objects (YSOs) located in the Ophiuchus and Uppe…
