Abstract

Losing weight with SODA: the impact of environment on disk properties in Orion A

Highlights

  • ALMA surveys of disks in nearby starforming regions have shown a dependence of the disk mass distribution on cloud properties and environmental factors

  • Due to the relatively small number of regions for which these statistics are available, several key questions have so far been out of reach for observers: do disk masses vary across clouds, or are they constant? How far does the influence of massive young stars reach in different environments? How do the masses of Class II-disks compare to those of embedded objects?

  • We present new results from the Survey of Orion Disks with ALMA (SODA), based on observations of 882 disks in the southern part of the Orion A molecular cloud

Summary

Introduction

Different ALMA surveys in individual star forming regions have significantly improved our understanding of the evolution of protoplanetary disks in recent times. Losing weight with SODA: the impact of environment on disk properties in Orion A ALMA surveys of disks in nearby starforming regions have shown a dependence of the disk mass distribution on cloud properties and environmental factors.
