THE SHORT ROTATION PERIOD OF HI’IAKA, HAUMEA’S LARGEST SATELLITE [PDF]
, 2016 Hi’iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysis, we have identified the rotation period of Hi’iaka to be ∼9.8 hr (double

THE INCREASING ROTATION PERIOD OF COMET 10P/TEMPEL 2 [PDF]
, 2010 We imaged comet 10P/Tempel 2 on 32 nights from 1999 April through 2000 March. R-band light curves were obtained on 11 of these nights from 1999 April through 1999 June, prior to both the onset of significant coma activity and perihelion.

The interior rotation of a sample of gamma Doradus stars from ensemble modelling of their gravity mode period spacings [PDF]
, 2016 CONTEXT. Gamma Doradus stars (hereafter gamma Dor stars) are known to exhibit gravity- and/or gravito-intertial modes that probe the inner stellar region near the convective core boundary.

Solar differential rotation in the period 1964–2016 determined by the Kanzelhöhe data set [PDF]
, 2017 The main aim of this work is to determine the solar differential rotation by tracing sunspot groups during the period 1964-2016, using the Kanzelhohe Observatory for Solar and Environmental Research (KSO) sunspot drawings and white light images.

Features of the mass transfer in magnetic cataclysmic variables with fast-rotating white dwarfs
EPJ Web of Conferences, 2014 The flow structure in magnetic cataclysmic variables was investigated taking into account the effects of strong magnetic field and fast rotation of the white dwarf. We modeled the AE Aqr system as a unique object that has the rotation period of the white

Analysis of the rotation period of asteroids (1865) Cerberus, (2100) Ra-Shalom, and (3103) Eger – search for the YORP effect [PDF]
, 2012 Context. The spin state of small asteroids can change on a long timescale by the Yarkovsky-O’Keefe-Radzievskii-Paddack (YORP) effect, the net torque that arises from anisotropically scattered sunlight and proper thermal radiation from an irregularly ...

How rotation affects masses and ages of classical Cepheids
EPJ Web of Conferences, 2017 Classical Cepheid variable stars are both sensitive astrophysical laboratories and accurate cosmic distance tracers. We have recently investigated how the evolutionary effects of rotation impact the properties of these important stars and here provide an

New rotation period measurements of 67,163 Kepler stars [PDF]
Astronomy & Astrophysics, 2023 The Kepler space telescope leaves a legacy of tens of thousands of stellar rotation period measurements. While many of these stars show strong periodicity, there exists an even bigger fraction of stars with irregular variability for which rotation ...
