Probing the Possible Causes of the Transit Timing Variation for TrES-2b in the TESS Era

open access: yesThe Astronomical Journal
Nowadays, transit timing variations (TTVs) are proving to be a very valuable tool in exoplanetary science to detect exoplanets by observing variations in transit times. To study the TTV of the hot Jupiter TrES-2b, we have combined 64 high-quality transit

Transit Depth Variations Reveal TOI-216 b to be a Super-puff

open access: yesThe Astronomical Journal, 2023
The planets of the TOI-216 system have been previously observed to exhibit large transit-timing variations, which enabled precise mass characterization of both transiting planets.

The Advantages of Global Photometric Models in Fitting Transit Variations

open access: yesThe Astronomical Journal, 2023
Estimation of planetary orbital and physical parameters from light-curve data relies heavily on the accurate interpretation of Transit Timing Variation (TTV) measurements.

Constraining the Densities of the Three Kepler-289 Planets with Transit Timing Variations

open access: yesThe Astronomical Journal, 2023
Kepler-289 is a three-planet system containing two sub-Neptunes and one cool giant planet orbiting a young, Sun-like star. All three planets exhibit transit timing variations (TTVs), with both adjacent planet pairs having orbital periods close to the 2:1

TESS Timings of 31 Hot Jupiters with Ephemeris Uncertainties

open access: yesThe Astrophysical Journal Supplement Series, 2023
A precise transit ephemeris serves as the premise for follow-up exoplanet observations. We compare TESS Object of Interest (TOI) transit timings of 262 hot Jupiters with the archival ephemeris and find 31 of them having TOI timing offsets, among which ...

The TESS-Keck Survey. XV. Precise Properties of 108 TESS Planets and Their Host Stars

open access: yesThe Astronomical Journal, 2023
We present the stellar and planetary properties for 85 TESS Objects of Interest (TOIs) hosting 108 planet candidates that compose the TESS-Keck Survey (TKS) sample.

Metrics for Optimizing Searches for Tidally Decaying Exoplanets

open access: yesThe Astronomical Journal, 2023
Tidal interactions between short-period exoplanets and their host stars drive orbital decay and have likely led to engulfment of planets by their stars.

Dynamics and Origins of the Near-resonant Kepler Planets

open access: yesThe Astrophysical Journal, 2023
Short-period super-Earths and mini-Neptunes encircle more than ∼50% of Sun-like stars and are relatively amenable to direct observational characterization.

Searching for Transit Timing Variations in Young Transiting Systems

open access: yesThe Astronomical Journal
The discovery of young (4 σ ), although differences in methodology make a totally fair comparison challenging. We show that spots have a weak-to-negligible impact on our results, and similarly cannot explain the higher TTV fraction.

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.
