Abstract:
We report the discovery and complex analyses of the first two compact
hierarchical triple star systems discovered with TESS in or near its
southern continuous viewing zone during Year 1. Both TICs 167692429
and 220397947 were previously unknown eclipsing binaries, and the
presence of a third companion star was inferred from eclipse timing
variations exhibiting signatures of strong third-body perturbations
and, in the first system, also from eclipse depth variations. We
carried out comprehensive analyses, including the simultaneous
photodynamical modelling of TESS and archival ground-based WASP light
curves, as well as eclipse timing variation curves. Also, for the
first time, we included in the simultaneous fits multiple star
spectral energy distribution data and theoretical PARSEC stellar
isochrones, taking into account Gaia DR2 parallaxes and catalogued
metallicities. We find that both systems have twin F-star binaries and
a lower mass tertiary star. In the TIC 167692429 system, the inner
binary is moderately inclined (imut=27°) with respect to the
outer orbit, and the binary versus outer (triple) orbital periods are
10.3 versus 331d, respectively. The mutually inclined orbits cause a
driven precession of the binary orbital plane that leads to the
disappearance of binary eclipses for long intervals. In the case of
TIC 220397947, the two orbital planes are more nearly aligned and the
inner versus outer orbital periods are 3.5 and 77d, respectively. In
the absence of radial velocity observations, we were unable to
calculate highly accurate masses and ages for the two systems.
According to stellar isochrones TIC 167692429 might be either a
pre-main sequence (MS) or an older post-MS system. In the case of TIC
220397947, our solution prefers a young pre-MS scenario.
Description:
TIC 167692429 was observed by the TESS spacecraft (Ricker et al.
2015JATIS...1a4003R 2015JATIS...1a4003R) during Year 1 in short cadence (SC) mode nearly
continuously with the exception of Sector 5. TIC 220397947 was
observed by TESS during Sectors 2-6, 8, 9, and 12. SC light curves are
available only from Sectors 3, 4, 9, and 12. SC light curves of these
targets were downloaded from the MAST Portal
(https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html).
Both TICs 167692429 and 220397947 are amongst the millions of stars
that have been observed as part of the WASP survey. The survey is
described in Pollacco et al. (2006PASP..118.1407P 2006PASP..118.1407P) and Collier Cameron
et al (2006MNRAS.373..799C 2006MNRAS.373..799C). Images are obtained through a broad-band
filter covering 400-700nm.
We utilized a combination of SED data, PARSEC theoretical stellar
isochrones (Bressan et al. 2012MNRAS.427..127B 2012MNRAS.427..127B) and photodynamical
model solutions to determine the stellar masses and temperatures. In
order to do this, we took compiled J, H, Ks, W1, and W2
magnitudes from the eighth version of the TESS Input Catalog (TIC-8;
Stassun et al. 2018AJ....156..102S 2018AJ....156..102S, Cat. IV/39), which in turn
subsumes photometric data from a large number of other photometric
catalogues such as the Two-Micron All-sky Survey (2MASS; Skrutskie et
al. 2006AJ....131.1163S 2006AJ....131.1163S, Cat. VII/233), and Wide-field Infrared Survey
Explorer (WISE; Cutri et al. 2013wise.rept....1C, Cat. II/328).
Moreover, we collected Johnson B, V, and Sloan g', r', i' magnitudes
from the ninth data release of the AAVSO Photometric All-Sky Survey
(APASS9; Henden et al. 2015AAS...22533616H, Cat. II/336) and also
BT, VT magnitudes from Tycho-2 catalogue (Hog et al.
2000A&A...355L..27H 2000A&A...355L..27H, Cat. I/259). Furthermore, we also utilized Gaia
G, BP, and RP magnitudes, and trigonometric parallax taken from
Gaia DR2 (Gaia collaboration 2018A&A...616A...1G 2018A&A...616A...1G, Cat. I/345).
Finally, we also took from TIC-8 the metallicity [M/H] obtained from
the spectroscopic survey TESS-HERMES DR-1 (Sharma et al.
2018MNRAS.473.2004S 2018MNRAS.473.2004S, Cat. J/MNRAS/473/2004).

Global Notes:
Note (G1): As Ω1=0° was assumed at epoch t0 for all runs,
Ω2 set the initial trial value of the differences of the
nodes (i.e. ΔΩ), which is the truly relevant parameter
for dynamical modelling.
Note (G2): Values interpolated from the PARSEC isochrones
