High speed photometry of faint Cataclysmic Variables: IV. V356 Aql, Aqr1, FIRST J1023+0038, Ha 0242-2802, GI Mon, AO Oct, V972 Oph, SDSS 0155+00, SDSS 0233+00, SDSS 1240-01, SDSS 1556-00, SDSS 2050-05, FH Ser

, 2004
We present results from high speed photometry of a further thirteen faint cataclysmic variables. V356 Aql (Nova Aql 1936) shows flare-like outbursts with recurrence time scales ~ 3000 s, but no coherent periodicities. Aqr1 is an intermediate polar with a

Carving Out the Inner Edge of the Period Ratio Distribution through Giant Impacts

The Astrophysical Journal
The distribution of orbital period ratios between adjacent observed exoplanets is approximately uniform, but exhibits a strong falloff toward close orbital separations.

About origin of comet 55P

Вісник Астрономічної школи, 2014
55P is a periodic comet with an orbital period of 33 years. It fits the classical definition of a Halley-type comet. The comet is the parent body of the Leonid meteor shower. Orbital simulation of the comet’s 55P/Tempel-Tuttle orbit for 5000 years before

A Robust Measure of Tidal Circularization in Coeval Binary Populations: The solar-type spectroscopic Binary Population in The Open Cluster M35

, 2004
We present a new homogeneous sample of 32 spectroscopic binary orbits in the young (~ 150 Myr) main-sequence open cluster M35. The distribution of orbital eccentricity vs.

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.

Validating the Orbital Periods of the Coolest TESS Planet Candidates

The Astronomical Journal
When an exoplanet passes in front of its host star, the resulting eclipse causes an observable decrease in stellar flux, and when multiple such transits are detected, the orbital period of the exoplanet can be determined. Over the past seven years NASA’s

Magnetic asynchronous nova V1500 Cyg in an "EARLY" and a "MEADLE" post-nova state

Odessa Astronomical Publications, 2017
A detailed analysis of photometric observations of magnetic nova V15OO Cyg in the ”early” (1978-1988) and ”middle” post-nova state (2000-2002) is presented.
