Description

TFOP Sub-Group 1 is dedicated to the confirmation/rejection of TESS candidates with seeing-limited ground-based photometry. We present the contribution of the TRAPPIST and SPECULOOS networks of robotic telescopes to this effort. The two TRAPPIST 60cm telescopes and the six SPECULOOS 1m telescopes have pixel scales ~0.65 arcsec and ~0.35 arcsec, respectively. These telescopes can perform seeing-limited sub-mmag photometry for I-magitude ranging from 8.5 to 14 (for TRAPPIST) and from 9.5 to 15 (for SPECULOOS). Up to 50% of the TRAPPIST telescope time is dedicated to the TESS follow-up, and it has enabled so far the observation of more than 200 TESS candidates. Similarly, up to 20% of SPECULOOS observing time is dedicated to the TESS follow-up, with more than 35 candidates observed to this day. Finally, we present our upcoming validation papers led by TRAPPIST or SPECULOOS team members.
