TOI-6695: A Pair of Near-resonant Massive Planets Observed with TESS from the WINE Survey

The Astronomical Journal
We present the discovery and characterization of a pair of warm Jovian-mass exoplanets orbiting the Sun-like star TOI-6695, based on Transiting Exoplanet Survey Satellite (TESS) transits and precise radial velocity (RV) measurements obtained with FEROS ...

HD 209458 planetary transits from Hipparcos photometry

, 2000
During its 39-month mission, Hipparcos observed the star HD 209458 on 89 occasions. Five of these observations are shown to correspond to epochs of planetary transits, with a 2.3±0.4% mean decrease of flux in the Hpband being observed during the transits.

Leaf Nutrient Remobilization and Its Relationship With Root Growth in Arabica Coffee

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
The flow of nutrients from mature leaves to priority sinks as young leaves and roots is one of the strategies for efficient use of nutrients. This study aimed to evaluate the relative remobilization (RR) of N, P, K, Mg, Cu, Fe, and Zn from mature to young leaves during the development stages of coffee fruits and its relationship with root growth in ...

TOI-4504: Exceptionally Large Transit Timing Variations Induced by Two Resonant Warm Gas Giants in a Three-planet System

The Astrophysical Journal Letters
We present a joint analysis of transit timing variations (TTVs) and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known TTVs, with a peak-to-node amplitude of ∼2 days, the ...

A Transiting Giant on a 7.7 yr Orbit Revealed by Transit Timing Variations in the TOI-201 System

The Astrophysical Journal Letters
We report the detection and characterization of TOI-201 c, a long-period transiting companion to the warm Jupiter TOI-201 b. Its presence was first inferred from high-amplitude transit timing variations (TTVs) in TOI-201 b, pointing to a massive outer ...
