Orbital period change of Dimorphos due to the DART kinetic impact. [PDF]
Nature, 2023 The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of near-Earth binary asteroid (65803) Didymos, and changing the orbital ...

Discovery of orbital eccentricity and evidence for orbital period increase of SS433 [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2021 The examination of long-term (1979–2020) photometric observations of SS433 enabled us to discover a non-zero orbital eccentricity of e = 0.05 ± 0.01. We have also found evidence for a secular increase in the orbital period at a rate of $\dot{P}_\mathrm{

Post-common envelope binaries from SDSS - XVI. Long orbital period systems and the energy budget of common envelope evolution [PDF]
, 2012 Virtually all close compact binary stars are formed through common-envelope (CE) evolution. It is generally accepted that during this crucial evolutionary phase a fraction of the orbital energy is used to expel the envelope.

Orbital period changes and the higher-order multiplicity fraction amongst SuperWASP eclipsing binaries [PDF]
, 2015 Orbital period changes of binary stars may be caused by the presence of a third massive body in the system. Here we have searched the archive of the Wide Angle Search for Planets (SuperWASP) project for evidence of period variations in 13 927 eclipsing ...

The first photometric and orbital period investigation of an extremely low mass ratio contact binary with a sudden period change, TYC 4002-2628-1 [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Photometric observations for the totally eclipsing binary system TYC 4002-2628-1, were obtained between November 2020 and November 2021. To determine the stellar atmospheric parameters, a spectral image was taken with the 2.16 m telescope at National ...

Orbital Period Refinement of CoRoT Planets with TESS Observations
Frontiers in Astronomy and Space Sciences, 2021 CoRoT was the first space mission dedicated to exoplanet detection. Operational between 2007 and 2012, this mission discovered 37 transiting planets, including CoRoT-7b, the first terrestrial exoplanet with a measured size. The precision of the published
