Circumstellar disks during various evolutionary stages

TL;DR

This paper reviews recent high-resolution observations of circumstellar disks across different stellar evolutionary stages, highlighting detection methods and their implications for star formation and evolution.

Contribution

It provides a comprehensive overview of current observational techniques and findings related to circumstellar disks from pre-Main Sequence to evolved stars.

Findings

Advances in high spatial and spectral resolution imaging.

Comparison of direct and indirect disk detection methods.

Disk properties vary across stellar evolutionary stages.

Abstract

Disks are ubiquitous in stellar astronomy, and play a crucial role in the formation and evolution of stars. In this contribution we present an overview of the most recent results, with emphasis on high spatial and spectral resolution. We will start with a general discussion on direct versus indirect detection of disks, and then traverse the HR diagram starting with the pre-Main Sequence and ending with evolved stars.
