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 ...

Methods for reliable estimation of pulse transit time and blood pressure variations using smartphone sensors

open access: yesMicroprocessors and Microsystems, 2016
Hypertension is known to affect around one third of adults globally and early diagnosis is essential to reduce the effects of this affliction. Todays Blood Pressure (BP) monitoring cuffs are obtrusive and inconvenient for performing regular measurements, and continuous non-invasive blood pressure devices are too complex and expensive for ambulatory use.

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.

Genomic Diversity and Clinical Variability in Pediatric Primary Cutaneous Anaplastic Large Cell Lymphoma: A Case Series

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.

Doomed Worlds. II. Reassessing Suggestions of Orbital Decay for TrES-5 b

open access: yesThe Planetary Science Journal
TrES-5 b is one of only three ultrahot Jupiters with suggestions of a possibly decreasing orbital period that have persisted through multiple independent analyses.
