Ultraviolet Imaging of SR 12 c with HST/WFC3: Accretion and Variability of a Giant Planet at the End Stages of Growth
Claire O. Finley, Brendan P. Bowler, Ya-Lin Wu +12
Many details of the gas accretion phase during giant planet formation remain untested. We present new 0.2$\unicode{x2013}$0.7 m UV-through-red optical imaging of the young, wide…
The long-term outburst(s) of GPSV16: from an intermediate to a FUor classification
Carlos Contreras Peña, Jeong-Eun Lee, Philip W. Lucas +8
FU Ori outbursts are thought to play a key role in stellar mass assembly and in the chemistry of protoplanetary disks during the early formation of stars. However, uncertainties re…
EPISODE IV: Ice Inventory in the Envelope of EC 53
Jaeyeong Kim, Jeong-Eun Lee, Chul-Hwan Kim +9
We present the 1.628 m spectra of the young protostar EC 53, obtained with JWST NIRSpec IFU and MIRI MRS during the quiescent and burst phases of its periodic brightness vari…
Direct evidence for magnetohydrodynamic disk winds driving rotating outflows in protostar HOPS 358
Chul-Hwan Kim, Jeong-Eun Lee, Doug Johnstone +4
Angular momentum removal is a fundamental requirement for star and planet formation, yet the mechanisms driving this process remain debated. Magnetohydrodynamic disk winds, launche…
Probing Dust in the MWC 480 Disk from Millimeter to Centimeter Wavelengths
Yangfan Shi, Feng Long, Enrique Macías +12
We present deep, high-resolution (100 mas) Karl G. Jansky Very Large Array (VLA) Ka-band (9.1 mm) observations of the disk around MWC 480, and infer dust properties through a…
EPISODE III: The Nested Jet/Outflow Morphology of EC 53 Revealed by JWST and ALMA
Seonjae Lee, Jeong-Eun Lee, Chul-Hwan Kim +8
We present an extensive study of the structure and kinematics of the jet and outflow of EC 53, a Class I protostar with a quasi-periodic variability, using combined James Webb Spac…
The mass distribution of clumpy accretion onto the nearby young star TW Hya
Tao Ji, Javier Serna, Gregory J. Herczeg +12
The proliferation of high time-resolution and decades-long monitoring of classical T Tauri stars provides a vast opportunity to test the variability of the star-disk connections. H…
Sub-millimeter wavelength protostellar accretion rate monitoring with AtLAST
Thomas Stanke, Verena Wolf, Bringfried Stecklum +5
How a star forms is a fundamental question in astrophysics. In the earliest stages of protostellar evolution high extinction prevents a direct study of the accretion processes and…
Characterizing the Low-Mass Pre-Main-Sequence Population in the Low-Metallicity Star-Forming Region Dolidze 25 Using VLT-MUSE
Mizna Ashraf, Jessy Jose, Gregory J. Herczeg +6
The metallicity of the star-forming environment is a fundamental parameter shaping the evolution of protoplanetary disks and the formation of planetary systems, yet its influence r…
YSO Variability in the W51 Star-Forming Region
Mi-Ryang Kim, Jeong-Eun Lee, Contreras Peña Carlos +3
Time-domain studies of mid-infrared and submillimeter variability have shown that at least half of protostars are variable. We present a statistical analysis of mid-infrared variab…
The Outbursting YSOs Catalogue (OYCAT)
C. Contreras Peña, J. -E. Lee, G. Herczeg +39
YSOs can display unpredictable and high-amplitude rises in brightness that can last from a few months to possibly over 100 years. These types of outbursts are explained by large ch…
Revealing Ionization Conditions of Sz 102 with Spatially Resolved [Ne III] Microjets
Chun-Fan Liu, Hsien Shang, Gregory J. Herczeg +1
Forbidden neon emission lines from small-scale microjets can probe high-energy processes in low-mass young stellar systems. We obtained spatially resolved [Ne III] spectra of the m…
Dual-Wavelength ALMA Observations of Dust Rings in Protoplanetary Disks
Feng Long, Paola Pinilla, Gregory J. Herczeg +13
We present new Atacama Large Millimeter/submillimeter Array (ALMA) observations for three protoplanetary disks in Taurus at 2.9\,mm and comparisons with previous 1.3\,mm data both…
Inner disk structure of the classical T Tauri star LkCa 15
S. H. P. Alencar, J. Bouvier, J. -F. Donati +15
Magnetospheric accretion has been thoroughly studied in young stellar systems with full non-evolved accretion disks, but it is poorly documented for transition disk objects with la…
Gaps and Rings in an ALMA Survey of Disks in the Taurus Star-forming Region
Feng Long, Paola Pinilla, Gregory J. Herczeg +23
Rings are the most frequently revealed substructure in ALMA dust observations of protoplanetary disks, but their origin is still hotly debated. In this paper, we identify dust subs…
