# Catalog of New K2 Exoplanet Candidates from Citizen Scientists

## TL;DR

This paper presents a catalog of 28 new exoplanet candidates from K2 data, identified through citizen science efforts, including a notable multi-planet system, enhancing understanding of exoplanet diversity and multiplicity.

## Contribution

The study introduces a new catalog of 28 K2 exoplanet candidates vetted by citizen scientists, including the discovery of a multi-planet system with near-resonant sub-Neptune planets.

## Key findings

- 28 new exoplanet candidates identified
- Discovery of a multi-planet system in near 3:2 resonance
- Candidates have RV amplitudes within current detection capabilities

## Abstract

We provide 28 new planet candidates that have been vetted by citizen scientists and expert astronomers. This catalog contains 9 likely rocky candidates ($R_{pl} < 2.0R_\oplus$) and 19 gaseous candidates ($R_{pl} > 2.0R_\oplus$). Within this list we find one multi-planet system (EPIC 246042088). These two sub-Neptune ($2.99 \pm 0.02R_\oplus$ and $3.44 \pm 0.02R_\oplus$) planets exist in a near 3:2 orbital resonance. The discovery of this multi-planet system is important in its addition to the list of known multi-planet systems within the K2 catalog, and more broadly in understanding the multiplicity distribution of the exoplanet population (Zink et al. 2019). The candidates on this list are anticipated to generate RV amplitudes of 0.2-18 m/s, many within the range accessible to current facilities.
