Correlation of Inflow Fluctuations with Episodic Accretion

Determine how fluctuations in large-scale inflow correlate with episodic accretion events onto individual protostars by conducting time-resolved spectroscopic monitoring that links inflow variability to accretion burst signatures.

Background

On intermediate scales (102–103 au), MOS observations can trace envelopes, winds, and jets, enabling detection of episodic ejection and shock-excited knots tied to discrete accretion bursts. The study aims to bridge cloud dynamics with inner-disk accretion behavior.

Here are the major open questions that the next big telescope developed by ESO will address through conducting a decadal spectroscopic survey of YSOs: How do inflow fluctuations correlate with episodic accretion events onto individual protostars?

Hence, we cannot conclude on the fate of this object as more observations are needed for two reasons.
