The FU Ori outburst of PR Ori B
Carlos Contreras Pena, Zsofia Nagy, Gregory Herczeg +42
We report the discovery of a nearby FU Ori-type outburst (FUor), PR Ori B, in the L1641 cluster of the Orion star-forming region. The high-amplitude variability was first identifie…
Radio Continuum and Water Maser Monitoring of the Outburst in HOPS 373: Free-Free Emission Does Not Respond to the Outburst
John Tobin, Doug Johnstone, Greg Herczeg +5
We present VLA C-band (5~cm) continuum, K-band (1.3~cm) continuum, and water maser (22.235 GHz) monitoring of the protostar HOPS-373. We additionally present the contemporaneous mo…
"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 SPHEREx Target List of Ice Sources (SPLICES)
Matthew L. N. Ashby, Joseph L. Hora, Kiran Lakshmipathaiah +16
One of the primary objectives of the SPHEREx mission is to understand the origin of molecules such as H2O, CO2, and other volatile compounds at the early stages of planetary system…
Photometric and Spectroscopic monitoring of YSOs in nearby star forming regions. I. Eruptive YSOs
Carlos Contreras Peña, Gregory J. Herczeg, Mizna Ashraf +7
Mid-infrared (mid-IR) variability in young stellar objects (YSOs) is driven by several physical mechanisms, which produce a variety of amplitudes and light curve shapes. One of the…
Diagnosing FUor-like Sources: The Parameter Space of Viscously Heated Disks in the Optical and Near-IR
Hanpu Liu, Gregory J. Herczeg, Doug Johnstone +8
FU Ori type objects (FUors) are decades-long outbursts of accretion onto young stars that are strong enough to viscously heat disks so that the disk outshines the central star. We…
A Gaia view on the star formation in the Monoceros OB1 and R1 associations
Beomdu Lim, Yael Naze, Jongsuk Hong +5
Stellar kinematics provides the key to understanding star formation process. In this respect, we present a kinematic study of the Monoceros OB1 (Mon OB1) and R1 (Mon R1) associatio…
Dissecting the different components of the modest accretion bursts of the very young protostar HOPS 373
Sung-Yong Yoon, Gregory J. Herczeg, Jeong-Eun Lee +11
Observed changes in protostellar brightness can be complicated to interpret. In our JCMT~Transient monitoring survey, we discovered that a young binary protostar, HOPS 373, is unde…
Evidence of Accretion Burst: The Viscously Heated Inner Disk of the Embedded Protostar IRAS 16316-1540
Sung-Yong Yoon, Jeong-Eun Lee, Seokho Lee +5
Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to thei…
High-resolution spectroscopic monitoring observations of FU Orionis-type object, V960 Mon
Sunkyung Park, Jeong-Eun Lee, Tae-Soo Pyo +9
We present the results of high-resolution (R 30,000) optical and near-infrared spectroscopic monitoring observations of a FU Orionis-type object, V960 Mon, which underwent an…
The ice composition in the disk around V883 Ori revealed by its stellar outburst
Jeong-Eun Lee, Seokho Lee, Giseon Baek +6
Complex organic molecules (COMs), which are the seeds of prebiotic material and precursors of amino acids and sugars, form in the icy mantles of circumstellar dust grains but canno…
