Accretion Properties of the Young Brown Dwarf 2MASS J08440915-7833457
Toni V. Panzera, Laura S. Flagg, Margaret A. Mueller +2
We present HST-COS FUV and -STIS optical observations towards the young accreting brown dwarf 2MASS-J08440915-7833457 (J0844) from the ULLYSES DDT Program. We analyse hot FUV lines…
The Near-Ultraviolet Spectra of FU Orionis Accretion Disks
Adolfo S. Carvalho, Lynne A. Hillenbrand, Gregory J. Herczeg +1
We present the results of the first high-sensitivity NUV (1800 to 3200 Ã ) survey of FU Ori objects, using the \textit{Hubble Space Telescope} (HST) STIS spectrograph. We compare n…
A comprehensive Gaia spectroscopic study of stars in the Sco-Cen complex: star formation history and disk lifetime
Min Fang, Gregory J. Herczeg
We re-evaluate the star formation history of the nearby Sco-Cen OB Association with a comprehensive analysis of Gaia XP spectra of more than 7,800 potential members. New spectral c…
Scientific Objectives of the Xue-shan-mu-chang 15-meter Submillimeter Telescope
XSMT Project Collaboration Group, Yiping Ao, Jin Chang +48
Submillimeter astronomy is poised to revolutionize our understanding of the Universe by revealing cosmic phenomena hidden from optical and near-infrared observations, particularly…
"Oh FUors where art thou": A search for long-lasting YSO outbursts hiding in infrared surveys
Carlos Contreras Peña, Jeong-Eun Lee, Ho-Gyu Lee +11
Long-lasting episodes of high accretion can strongly impact stellar and planetary formation. However, the universality of these events during the formation of young stellar objects…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
