Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

The Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.

COMPARISON OF GPS SATELLITE COORDINATES COMPUTED FROM BROADCAST AND IGS FINAL EPHEMERIDES

, 2018
There are mainly two different orbital information, namely broadcast ephemerides and IGS final ephemerides (IGS rapid, ultra rapid, predicted and final ephemerides) used in the GPS positioning. The broadcast ephemerides used in practice and real time are

Real-time precise measurements of ocean surface waves using GNSS variometric approach

International Journal of Applied Earth Observations and Geoinformation, 2022
The global navigation satellite system (GNSS) wave buoys currently in use can measure ocean surface waves but have major drawbacks regarding their real-time high-precision application due to the communication burden and high differential correction ...

FO Aqr time keeping [PDF]

arXiv, 2016
Twelve seasons, from 2004 to 2015, of photometric monitoring of the intermediate polar FO Aqr are presented and are compared with previous observations. The ambiguities in the cycle counting can be lifted and a new O-C diagram, spanning 34 yr, is presented, along with new ephemerides.

Teorie lunari, effemeridi e sistemi di coordinate (Lunar theories, ephemerides and coordinates systems) [PDF]

arXiv, 2012
This work deals with the comparison of different parameters (French/IMCCE and US/JPL ephemerides) used to calculate the extension of the umbral shadow and the location of the centre line in the total solar eclipse that took place on March, 29th 2006.
