The Transit Timing and Transmission Spectrum of Hot Jupiter WASP-43 b from a Decade of Multiband Transit follow-up Observations

The Astronomical Journal
We present a new set of 35 transit light curves of the hot Jupiter WASP-43 b, obtained through the SPEARNET network. These datasets were analyzed together with previously published ground-based observations, as well as space-based data from TESS, Hubble ...

Ionospheric measurements of relative coronal brightness during the total solar eclipses of 11 August, 1999 and 9 July, 1945 [PDF]

Annales Geophysicae, 2000
Swept-frequency (1-10 MHz) ionosonde measurements were made at Helston, Cornwall (50°06'N, 5°18'W) during the total solar eclipse on August 11, 1999. Soundings were made every three minutes.

Inferring Exoplanet Parameters from Transit Timing Variations Using LSTM Networks

The Planetary Science Journal
Transit timing variation (TTV) analysis provides a valuable complement to traditional transit and radial-velocity techniques, particularly in compact, near-resonant planetary systems where dynamical interactions amplify timing signals and refine mass and
