Inner warm disk of ESO H 279A revealed by NA I and CO overtone emission lines
A-Ran Lyo, Jongsoo Kim, Jae-Joon Lee +20
We present analysis of near-infrared, high-resolution spectroscopy towards the Flat-spectrum YSO (Young Stellar Object) ESO H 279a (1.5 solar mass) in the Serpens star forming…
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…
Direct Spectral Detection: An Efficient Method to Detect and Characterize Binary Systems
Kevin Gullikson, Adam Kraus, Sarah Dodson-Robinson +6
Young, intermediate-mass stars are experiencing renewed interest as targets for direct-imaging planet searches. However, these types of stars are part of multiple systems more ofte…
Composition of Giants 1 North of the Galactic Center: Detailed Abundance Trends for 21 Elements Observed with IGRINS
Govind Nandakumar, Nils Ryde, Gregory Mace +10
We report the first high resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within of the Galactic plane, where high extinction has rende…
Fluorine in the solar neighbourhood: the need for several cosmic sources
Nils Ryde, Henrik Jönsson, Gregory Mace +14
The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constr…
First Sample of H+[O III] 5007 Line Emitters at Through JWST/NIRCam Slitless Spectroscopy: Physical Properties and Line Luminosity Functions
Fengwu Sun, Eiichi Egami, Nor Pirzkal +26
We present a sample of four emission-line galaxies at that were serendipitously discovered using the commissioning data for the JWST/NIRCam wide-field slitless spectr…
