ALMA SOLAR EPHEMERIS GENERATOR [PDF]

open access: yesRudarsko-geološko-naftni Zbornik, 2019
An online software tool for the easy preparation of ephemerides of the solar surface features is presented. It was developed as a helper tool for the preparation of observations of the Sun with the Atacama Large Millimeter/submillimeter Array (ALMA), but

TESS Timings of 31 Hot Jupiters with Ephemeris Uncertainties [PDF]

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 K2 and TESS Synergy. III. Search and Rescue of the Lost Ephemeris for K2's First Planet [PDF]

open access: yesThe Astronomical Journal
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 ± 0.1 R _⊕ , 9.7 ± 1.2 M _⊕ ) orbiting a relatively bright ( K _S = 8.03) K-dwarf star on a 9.1 day period. Unfortunately, due
