A small star hosts a big planet

Science, 2019
Exoplanets M dwarfs, the most common type of star, are low-mass objects that emit most of their faint light in the near-infrared, making it difficult to detect any orbiting exoplanets. Morales et al. have observed the nearby M dwarf GJ 3512 in the optical and near-infrared (see the Perspective by Laughlin).

Winds of Planet Hosting Stars [PDF]

, 2017
The field of exoplanetary science is one of the most rapidly growing areas of astrophysical research. As more planets are discovered around other stars, new techniques have been developed that have allowed astronomers to begin to characterise them.

Planet Host Star Properties as Probes of Planet Formation and Evolution

2023
Over the past three decades, we have discovered over 5000 exoplanets that exhibit sizes, orbital architectures, and other properties that are often dramatically different from those of planets in our own Solar System. To understand the various processes that sculpted this diversity of planets, we can examine the stars they orbit.

Characterizing Planet Host Stars: Introduction

2018
If one is concerned about measuring accurate properties of exoplanets, one will need to measure stellar properties such as stellar mass, radius, mean density, surface effective temperature, distance, and age. In this chapter, a number of basic properties for exoplanets are listed, and their dependence on fundamental stellar properties is discussed. The

Application to Observations of Planet-Hosting Stars

2016
In this chapter, I present the work I have done towards characterising three planetary systems: CoRoT-7, Kepler-78 and Kepler-10. CoRoT-7 is an active star host to a small hot Neptune and the first Earth-size exoplanet ever discovered. Kepler-78 is an active star orbited by an extremely close-in hot, Earth-mass planet.
