3-D reconstructions of active stars - observations

TL;DR

This paper reviews advanced observational techniques and recent findings related to the surfaces and interiors of active stars, which are challenging to study due to their faintness and point-source nature.

Contribution

It provides a comprehensive overview of current methods and recent results in 3-D reconstructions of active stars' surfaces and interiors.

Findings

Summarizes state-of-the-art observational techniques.

Highlights recent discoveries in stellar surface features.

Discusses advances in 3-D stellar interior modeling.

Abstract

Stars are usually faint point sources and investigating their surfaces and interiors observationally is very demanding. Here I give a review on the state-of-the-art observing techniques and recent results on studying interiors and surface features of active stars.
