WISEA J052305.94-015356.1: A New EsdT Candidate
Samuel J. Goodman
TL;DR
This paper introduces a new candidate for an extremely metal-poor T subdwarf, identified through infrared colors and high proper motion, highlighting its potential as a member of a newly discovered class of substellar objects.
Contribution
The paper reports the discovery of WISEA J052305.94-015356.1 as a candidate esdT, expanding the known population of metal-poor substellar objects.
Findings
High proper motion suggests nearby substellar nature
Infrared colors indicate extremely metal-poor characteristics
Spectroscopic confirmation is pending
Abstract
I present WISEA J052305.94-015356.1 as a new candidate extremely metal-poor T subdwarf (esdT), based on its distinctive infrared colours and high proper motion (mas/yr). Spectroscopic follow-up is now needed to confirm it is a member of this newly discovered class of substellar objects.
