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.

Photometric Follow-up Observations of the Transiting Neptune-Mass Planet GJ 436b

, 2008
This paper presents multi-band photometric follow-up observations of the Neptune-mass transiting planet GJ 436b, consisting of 5 new ground-based transit light curves obtained in May 2007. Together with one already published light curve we have at hand a

Inferring Exoplanet Parameters from Transit Timing Variations Using LSTM Networks

The Planetary Science Journal
Transit timing variation (TTV) analysis provides a valuable complement to traditional transit and radial-velocity techniques, particularly in compact, near-resonant planetary systems where dynamical interactions amplify timing signals and refine mass and

Super-Earths: A New Class of Planetary Bodies

, 2011
Super-Earths, a class of planetary bodies with masses ranging from a few Earth-masses to slightly smaller than Uranus, have recently found a special place in the exoplanetary science.

A Decade of Transit-timing Measurements Confirm Resonance in the K2-19 System

The Astronomical Journal
K2-19 is a star, slightly smaller than the Sun, that hosts three transiting planets. Two of these, K2-19 b and c, are between the size of Neptune and Saturn and have orbital periods near a 3:2 commensurability, and exhibit strong transit-timing ...

A Ground-based Transit Observation of the Long-period Extremely Low-density Planet HIP 41378 f

The Astronomical Journal
We present a ground-based transit detection of HIP 41378 f, a long-period ( P = 542 days), extremely low-density (0.09 ± 0.02 g cm ^−3 ) giant exoplanet in a dynamically complex system.

Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d

The Astronomical Journal
LP 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 ...

Quantifying the challenges of detecting unseen planetary companions with transit timing variations

, 2010
Both ground and space-based transit observatories are poised to significantly increase the number of known transiting planets and the number of precisely measured transit times.

A Planet Candidate Orbiting near the Hot Jupiter TOI-2818 b Inferred through Transit Timing

The Astrophysical Journal
TOI-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

The Quasiperiodic Automated Transit Search Algorithm

, 2012
We present a new algorithm for detecting transiting extrasolar planets in time-series photometry. The Quasiperiodic Automated Transit Search (QATS) algorithm relaxes the usual assumption of strictly periodic transits by permitting a variable, but bounded,
