The Variation of Circumstellar Parameters through Early Stellar Evolution
Michael Connelley, Christian Flores, Bo Reipurth
We report on the evolution of extinction, mass accretion rate, and spectral index from analysis of SpeX observations and AllWISE spectral energy distributions, compared to stellar…
Using Gravity as an Age Indicator for Young Stars
Michael Connelley, Christian Flores, Bo Reipurth
The age of a young star is difficult to measure and yet is a fundamental property that is essential for understanding stellar evolution. Accurate age indicators across the early ph…
Probing the kinematics of FU Orionis objects through high-resolution near-infrared spectroscopy
Ellen Lee, Michael Connelley
FU Orionis (FUor) objects are thought to be described by a steady-state Keplerian disk. However, the characteristic double-peaked Keplerian line profile is not readily seen in most…
SPHEREx Discovery of Strong Water Ice Absorption and an Extended Carbon Dioxide Coma in 3I/ATLAS
C. M. Lisse, Y. P. Bach, S. Bryan +17
In mid-August 2025, 0.75-5.0 micron SPHEREx imaging spectrophotometric and ancillary NASA-IRTF SpeX 0.7-2.5 micron low-resolution spectral observations of Interstellar Object 3I AT…
Near-Discovery Observations of Interstellar Comet 3I/ATLAS with the NASA Infrared Telescope Facility
Theodore Kareta, Chansey Champagne, Lucas McClure +8
Interstellar Objects are comets and asteroids that formed around other stars but were ejected before they could accrete into exoplanets. They therefore represent a rare opportunity…
Spectroscopic Characterization of Interstellar Object 3I/ATLAS: Water Ice in the Coma
Bin Yang, Karen J. Meech, Michael Connelley +2
We present optical and near-infrared spectroscopy of the interstellar object 3I/ATLAS, obtained with Gemini-S/GMOS and NASA IRTF/SpeX on 2025 July 5 and July 14. The optical spectr…
FUOr-Aur 0544+3330: A New YSO Outburst in the Outskirts of Auriga OB1, Viewed Face-On
Lynne A. Hillenbrand, Adolfo S. Carvalho, Dan Stern +5
We present a newly appreciated FU Ori outburst event that began in 2019 and reached a peak in early 2021. Suspected young stellar object WISE J054452.25+333009.6 experienced substa…
