Discovery and multi-wavelength follow-up of a new FU Orionis accretion outburst in V7995 Sgr with photometry and spectroscopy confirming the classification.
High-contrast imaging of HD 142527 reveals a candidate companion at ~14 au and an Hα spiral in the inner disk, possibly tracing accretion flows linked to companion B.
FUor masses inferred from Keplerian line broadening in H-band spectra match the solar neighborhood IMF, indicating a universal eruptive phase during star formation.
No change detected in ice absorption bands of EC 53 between phases, with ice abundances higher than typical for embedded protostars.
One migrating planet produces multiple observable dust rings and gaps lasting ≥400 kyr; cooling controls jump number but not structure lifetime.
JWST spectra of EC 53 indicate CO fundamental and H2O bending absorption weaken by ~2 during burst due to continuum dilution, with relative veiling yielding hot-continuum ratios of 2.9 and 1.71 and viscous-disk accretion-rate ratios of ~3.6 and ~2.0.
Reanalysis of 79 solar twins indicates the Sun's chemical peculiarity is largely explained by Galactic chemical evolution, with 2-6 candidates possibly showing planetary engulfment.
A parameterized accretion disk model for young stellar objects predicts that optical and near-IR outburst light curves track the input accretion rate profile while mid-IR curves respond more to the location and heating of the innermost dust disk.
Gaia21bja is identified as a pre-main sequence star with quasi-periodic bursts, showing spectral features and a 5.5-6 times higher accretion rate during outbursts that place it in the periodic category of outbursting YSOs.
Two-epoch medium-band photometry of 769 YSO candidates in Orion A identifies 110 variables (~14%), with best-fit templates dominated by cold and hot spot models over extinction or gray changes.
The paper proposes the iSEEDs project to integrate machine learning with astrochemistry for extracting physical conditions and molecular abundances from protostellar disk datasets.
The paper reviews techniques for measuring protostellar accretion, analyzes methodological differences and caveats in comparing observations with simulations, and outlines next steps for a fuller picture.

EPISODE II: Variability in the CO and H$_2$O rovibrational absorption lines in a periodically variable protostar EC 53
JWST spectra of EC 53 indicate CO fundamental and H2O bending absorption weaken by ~2 during burst due to continuum dilution, with relative veiling yielding hot-continuum ratios of 2.9 and 1.71 and viscous-disk accretion-rate ratios of ~3.6 and ~2.0.
