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…

Constructing a Mock Galaxy Catalog for the All-sky SPECtroscopic Survey of Nearby Galaxies (A-SPEC) Using the Machine-assisted Semi-Simulation Model

Dongkok Kim, Yongseok Jo, Ho Seong Hwang +26

We present a methodology for constructing a mock galaxy catalog for the All-sky SPECtroscopic survey of nearby galaxies (A-SPEC) using the Machine-assisted Semi-Simulation Model. T…

EPISODE II: Variability in the CO and HO rovibrational absorption lines in a periodically variable protostar EC 53

Seokho Lee, Jeong-Eun Lee, Chul-Hwan Kim +19

We present two-epoch JWST NIRSpec and MIRI observations of the young protostar EC 53 (V371 Ser), a periodically variable source with well-characterized quiescent and burst phases.…

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…

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…

The SPHEREx Ices Investigation: An Overview

Gary J. Melnick, Joseph L. Hora, Matthew L. N. Ashby +26

SPHEREx is a NASA mission designed to perform an all-sky spectroscopic survey in the 0.75 - 5 m wavelength range. Its primary science objectives are to investigate: (1) inflatio…
