A backward-spinning star with two coplanar planets

no code implementations15 Feb 2021 Maria Hjorth, Simon Albrecht, Teruyuki Hirano, Joshua N. Winn, Rebekah I. Dawson, J. J. Zanazzi, Emil Knudstrup, Bun'ei Sato

In theory, star/disk misalignments can result from turbulence during star formation or the gravitational torque of a wide-orbiting companion star, but no definite examples of this scenario are known.

TOI-640 b is one of only three known hot Jupiters to have a highly inflated radius (R$_{\rm P}$ > 1. 7R$_{\rm J}$, possibly a result of its host star's evolution) and resides on an orbit with a period longer than 5 days.

We report the discovery of two short-period Saturn-mass planets, one transiting the G subgiant TOI-954 (TIC 44792534, $ V = 10. 343 $, $ T = 9. 78 $) observed in TESS Sectors 4 & 5, and one transiting the G dwarf EPIC 246193072 ($ V = 12. 70 $, $ K = 10. 67 $) observed in K2 Campaigns 12 & 19.

TESS full orbital phase curve of the WASP-18b system

1 code implementation14 Nov 2018 Avi Shporer, Ian Wong, Chelsea X. Huang, Michael R. Line, Keivan G. Stassun, Tara Fetherolf, Stephen R. Kane, Luke G. Bouma, Tansu Daylan, Maximilian N. Guenther, George R. Ricker, David W. Latham, Roland Vanderspek, Sara Seager, Joshua N. Winn, Jon M. Jenkins, Ana Glidden, Zach Berta-Thompson, Eric B. Ting, Jie Li, Kari Haworth

The phase curve includes the transit, secondary eclipse, and sinusoidal modulations across the orbital phase shaped by the planet's atmospheric characteristics and the star-planet gravitational interaction.
