Post-common envelope binaries from SDSS - XVI. Long orbital period systems and the energy budget of CE 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 Decay Candidates Reconsidered: WASP-4 b Is Not Decaying and Kepler-1658 b Is Not a Planet
The Planetary Science JournalThe fate of hot Jupiters is thought to be engulfment by their host stars, the outcome of tidal orbital decay. Transit timing has revealed a few systems with apparently shrinking orbital periods, but such signals can be mimicked by light travel-time ...

THE ROLE OF MAGNETIC STELLAR WIND AND MASS TRANSFER IN CLOSE BINARIES OF THE EARLY SPECTRAL TYPE
Odessa Astronomical Publications, 2017 We suggest the results of calculations of mass transfer rate using orbital period changing and changing of orbital semi-major axis due to magnetic stellar Wind and mass transfer in close binaries of early spectral type.

Advanced Functional Materials, EarlyView.A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...

NSV 13983: A New Dwarf Nova in the Period Gap
, 2008 Aims. NSV 13983 is catalogued as a dwarf nova based on a reported outburst from 2005. The system has not yet been studied spectroscopically. We attempt to confirm its nature as a dwarf nova and determine its orbital period. Methods.
