Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d
The Astronomical JournalLP 791-18 d is a temperate Earth-sized planet ( R _P = 1.03 R _⊕ , P = 2.76 days) orbiting a late M dwarf, with an interior super-Earth (LP 791-18 b, R _P = 1.2 R _⊕ , P = 0.95 days) and an exterior sub-Neptune (LP 791-18 c, R _P = 2.5 R _⊕ , P = 4.99 ...

A Planet Candidate Orbiting near the Hot Jupiter TOI-2818 b Inferred through Transit Timing
The Astrophysical JournalTOI-2818 b is a hot Jupiter orbiting a slightly evolved G-type star on a 4.04 day orbit that shows transit timing variations (TTVs) suggestive of a decreasing orbital period. In the most recent year of TESS observations, transits were observed ∼8 minutes

Observations and Studies on the Transiting Systems HAT-P-36, XO-2 and WASP-76
The Astronomical JournalWe conducted photometric observations for transit events of three exoplanetary systems HAT-P-36, XO-2 and WASP-76 using the 1 m and 2.4 m telescopes at Yunnan Observatories and the 0.85 m telescope at National Astronomical Observatories of China.

Investigating the physical properties of transiting hot Jupiters with the 1.5-m Kuiper Telescope
, 2017 We present new photometric data of 11 hot Jupiter transiting exoplanets (CoRoT-12b, HAT-P-5b, HAT-P-12b, HAT-P-33b, HAT-P-37b, WASP-2b, WASP-24b, WASP-60b, WASP-80b, WASP-103b, XO-3b) in order to update their planetary parameters and to constrain ...

Detailed Architecture of the L 98-59 System and Confirmation of a Fifth Planet in the Habitable Zone
The Astronomical JournalThe L 98-59 system, identified by TESS in 2019, features three transiting exoplanets in compact orbits of 2.253, 3.691, and 7.451 days around an M3V star, with an outer 12.83 day nontransiting planet confirmed in 2021 using ESPRESSO.

Detecting New Planets in Transiting Systems
, 2006 I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally spaced intervals in time.

The Kepler-19 System: A Transiting 2.2 R_⊕ Planet and a Second Planet Detected via Transit Timing Variations [PDF]
, 2011 We present the discovery of the Kepler-19 planetary system, which we first identified from a 9.3 day periodic transit signal in the Kepler photometry. From high-resolution spectroscopy of the star, we find a stellar effective temperature T_(eff) = 5541 ±

The Astrophysical Journal LettersWe report the discovery and characterization of a small planet, TOI-1408 c, on a 2.2 day orbit located interior to a previously known hot Jupiter, TOI-1408 b ( P = 4.42 days, M = 1.86 ± 0.02 M _Jup , R = 2.4 ± 0.5 R _Jup ) that exhibits grazing transits.

Degeneracy in the characterization of non-transiting planets from transit timing variations
, 2012 The transit timing variation (TTV) method allows the detection of non-transiting planets through their gravitational perturbations. Since TTVs are strongly enhanced in systems close to mean-motion resonances (MMR), even a low mass planet can produce an ...
