Abstract:
TOI-1899b is a rare exoplanet, a temperate warm Jupiter orbiting an
M-dwarf, first discovered by Canas et al. (2020) from a TESS
single-transit event. Using new radial velocities (RVs) from the
precision RV spectrographs HPF and NEID, along with additional TESS
photometry and ground-based transit follow-up, we are able to derive a
much more precise orbital period of
P=29.090312-0.000035+0.000036days, along with a radius of
Rp=0.99±0.03RJ. We have also improved the constraints on planet
mass, Mp=0.67±0.04MJ, and eccentricity, which is consistent with a
circular orbit at 2σ(e=0.044-0.027+0.029). TOI-1899b
occupies a unique region of parameter space as the coolest known
(Teq∼380K) Jovian-sized transiting planet around an M dwarf; we show
that it has great potential to provide clues regarding the formation
and migration mechanisms of these rare gas giants through transmission
spectroscopy with JWST, as well as studies of tidal evolution.
Description:
HPF is a fiber-fed, high-resolution (R∼50000), NIR (808-1278nm)
spectrograph, located at the 10m Hobby-Eberly Telescope (HET) at
McDonald Observatory.
TESS first observed TOI-1899 during Sectors 14 (2019 July 18-2019
August 14) and 15 (2019 August 15-2019 September 10) at 2-minute
cadence, revealing a single-transit event, which was used by Canas+,
2020AJ....160..147C 2020AJ....160..147C to derive the initial orbit of this planet. Since
then, TESS has reobserved TOI-1899 during Sectors 41 (2021 July
23-2021 August 20), 54 (2022 July 9-2022 August 4), and 55 (2022
August 5-2022 September 1), all at 2-minute cadence.
We observed a partial transit of TOI-1899b on the night of 2021
November 7 with the 17" (0.43m) PlaneWave Corrected Dall-Kirkham
(CDK) telescope at the Richard S. Perkin Observatory at Hobart &
William Smith Colleges. The Perkin 17" is mounted on a Paramount
equatorial mount and equipped with an SBIG 8300M camera at Cassegrain
focus. The detector array is 3326x2504 pixels, with a field of view
(FOV) of ∼21x16' , resulting in an unbinned pixel scale of
0.38"/pixel.
On the same night (2021 November 7), we also observed TOI-1899b with
the 24" (0.61m) PlaneWave CDK located on the roof of Penn State's
Davey Laboratory. Similar to the Perkin observations above, we were
only able to observe midtransit through egress. The Davey Lab 24" has
an SBIG STX-9000 camera with an array of 3056x3056pixels and an FOV of
∼32x32' , corresponding to an unbinned pixel scale of 0.63"/pixel.
We also observed a partial transit of TOI-1899b on the night of 2022
April 1 with the Astrophysical Research Consortium (ARC) Telescope
Imaging Camera (ARCTIC) on the ARC 3.5m Telescope at Apache Point
Observatory. (842-872nm). We operated ARCTIC in the quad-amplifier and
fast-readout modes, defocused to ∼5" FWHM and binned 4x4 with an
exposure time of 25s.
