# Massive stars, successes and challenges

## TL;DR

This paper reviews current understanding and challenges in the evolution and end-of-life processes of massive stars, focusing on convection, mass loss, rotation, magnetic fields, and multiplicity, highlighting their interactions and open questions.

## Contribution

It provides a comprehensive overview of the key physical processes affecting massive star evolution, emphasizing recent successes and ongoing challenges in the field.

## Key findings

- Interactions among physical processes lead to diverse stellar outcomes
- Many aspects of massive star evolution remain uncertain and require further research
- The review highlights areas where new discoveries are expected

## Abstract

We give a brief overview of where we stand with respect to some old and new questions bearing on how massive stars evolve and end their lifetime. We focus on the following key points that are further discussed by other contributions during this conference: convection, mass losses, rotation, magnetic field and multiplicity. For purpose of clarity, each of these processes are discussed on its own but we have to keep in mind that they are all interacting between them offering a large variety of outputs, some of them still to be discovered.
