Abstract:
We present the Distant Giants Survey, a three-year radial velocity
campaign to measure P(DG|CS), the conditional occurrence of distant
giant planets (DG; Mp∼0.3-13MJup, P>1yr) in systems hosting a
close-in small planet (CS; Rp<10R⊕). For the past two years, we
have monitored 47 Sun-like stars hosting small transiting planets
detected by TESS. We present the selection criteria used to assemble
our sample and report the discovery of two distant giant planets,
TOI-1669b and TOI-1694c. For TOI-1669b we find that
Msini=0.573±0.074MJup, P=502±16days, and e<0.27, while for
TOI-1694c, Msini=1.05±0.05MJup, P=389.2±3.9days, and
e=0.18±0.05. We also confirmed the 3.8 days transiting planet
TOI-1694b by measuring a true mass of M=26.1±2.2M⊕. At the
end of the Distant Giants Survey, we will incorporate TOI-1669b and
TOI-1694c into our calculation of P(DG|CS), a crucial statistic for
understanding the relationship between outer giants and small inner
companions.
Description:
We presented the Distant Giants Survey, and radial velocity study
designed to search for long-period giant companions to inner
transiting planets detected by Transiting Exoplanet Survey Satellite.
We reported the discovery of two outer giant planets, TOI-1669b and
TOI-1694c, identified using Keck-HIRES RVel.

Note on table4.dat: The effective temperatures, surface gravities,
metallicities, and rotational velocities we list here were calculated
using SpecMatch, which assigns a fixed uncertainty to each derived
parameter. Stellar masses incorporate isochrone constraints, as
described in Fulton & Petigura, 2018, J/AJ/156/264.
