# Exoplanet host-star properties: the active environment of exoplanets

## TL;DR

This paper discusses the ExoplANETS-A project which aims to understand exoplanet atmospheres and the influence of host star activity, providing new insights and early results from the EU-funded initiative.

## Contribution

It offers new knowledge on host star activity and its impact on exoplanet atmospheres, with initial findings from a comprehensive EU project.

## Key findings

- Early results on host star activity
- Insights into star-planet atmospheric interactions
- Development of online dissemination platforms

## Abstract

The primary objectives of the ExoplANETS-A project are to: establish new knowledge on exoplanet atmospheres; establish new insight on influence of the host star on the planet atmosphere; disseminate knowledge, using online, web-based platforms. The project, funded under the EU's Horizon-2020 programme, started in January 2018 and has a duration ~3 years. We present an overview of the project, the activities concerning the host stars and some early results on the host stars.
