ALMA Observations of a High-density Core, MC27/L1521F in Taurus: Dynamical Gas Interaction at the Possible Site of a Multiple Star Formation

TL;DR

This study uses ALMA observations to reveal complex spatial and velocity structures in a dense core, indicating highly dynamical initial conditions for star formation.

Contribution

It provides detailed ALMA data showing the complex dynamics of a dense core near the first core phase, highlighting the dynamical nature of early star formation.

Findings

Complex spatial and velocity structures observed

Initial conditions of star formation are highly dynamical

Supports the idea of dynamic early star formation processes

Abstract

We present the results of ALMA observations of dust continuum emission and molecular rotational lines toward a dense core, MC27 (aka L1521F), which is considered to be very close to the first core phase. We revealed the spatial/velocity structures of the core are very complex and and suggest that the initial condition of star formation is highly dynamical.
