Toward Direct Imaging of Low-Mass Gas-Giants with the $\textit{James Webb Space Telescope}$

TL;DR

This paper discusses preparing for JWST observations to directly image low-mass gas giants around young M dwarfs, highlighting the telescope's unprecedented sensitivity and potential scientific insights.

Contribution

It identifies new young M dwarf targets and assesses JWST's capabilities for direct imaging of sub-Jovian exoplanets around these stars.

Findings

JWST can routinely detect sub-Jovian planets around young M dwarfs.

The study provides an updated list of young M dwarf targets.

JWST's sensitivity will advance understanding of low-mass gas-giant properties.

Abstract

In preparation for observations with the $\textit{James Webb Space Telescope}$ ($\textit{JWST}$), we have identified new members of the nearby, young M dwarf sample and compiled an up to date list of these stars. Here we summarize our efforts to identify young M dwarfs, describe the current sample, and detail its demographics in the context of direct planet imaging. We also describe our investigations of the unprecedented sensitivity of the $\textit{JWST}$ when imaging nearby, young M dwarfs. The $\textit{JWST}$ is the only near term facility capable of routinely pushing direct imaging capabilities around M dwarfs to sub-Jovian masses and will provide key insight into questions regarding low-mass gas-giant properties, frequency, formation, and architectures.
