Rotation, spectral variability, magnetic geometry and magnetosphere of the Of?p star CPD -28 2561 [PDF]

, 2015
We report magnetic and spectroscopic observations and modeling of the Of?p star CPD -28 2561. Using more than 75 new spectra, we have measured the equivalent width variations and examined the dynamic spectra of photospheric and wind-sensitive spectral ...

Individual consistency in migration strategies of a tropical seabird, the Round Island petrel

Movement Ecology, 2022
Background In migratory species, the extent of within- and between-individual variation in migratory strategies can influence potential rates and directions of responses to environmental changes.

Mass flow in the circumbinary disk with gap around supermassive binary black holes

, 2013
In this paper, we study the interaction between the supermassive binary black holes in elliptical orbit and their surrounding disk with a gap. The gap in the disk is a low density region formed due to the tidal effects of the less massive black hole ...

Revisiting CoRoT RR Lyrae stars: detection of period doubling and temporal variation of additional frequencies [PDF]

, 2014
We search for signs of period doubling in CoRoT RR Lyrae stars. The occurrence of this dynamical effect in modulated RR Lyrae stars might help us to gain more information about the mysterious Blazhko effect.

Cassini UVIS Observations of the Io Plasma Torus. IV. Modeling Temporal and Azimuthal Variability

, 2007
In this fourth paper in a series, we present a model of the remarkable temporal and azimuthal variability of the Io plasma torus observed during the Cassini encounter with Jupiter.

Characteristics of Period Variation of Eclipsing Binary Star [PDF]

Journal of Astronomy and Space Sciences, 1993
Among the EA and semi-detached type binary systems, nineteen eclipsing binaries were investigated for their period variations from all of the collected times of minima available in the literature.

Periodicities in the coronal rotation and sunspot numbers

, 2011
The present study is an attempt to investigate the long term variations in coronal rotation by analyzing the time series of the solar radio emission data at 2.8 GHz frequency for the period 1947 - 2009. Here, daily adjusted radio flux (known as Penticton

An Irradiation Effect in Nova DN Gem 1912 and the Significance of the Period Gap for Classical Novae [PDF]

, 1999
Continuous CCD photometry of the classical nova DN Gem during 52 nights in the years 1992-98 reveals a modulation with a period 0.127844 d. The semi-amplitude is about 0.03 mag. The stability of the variation suggests that it is the orbital period of the

On the Period Variations of BH Virginis [PDF]

Publications of the Astronomical Society of Japan, 2008
Abstract In the present work, 17 new times of the light minimum for BH Vir were derived from observations by Kjurkchieva et al. (2004 , A&A, 424, 993). Combining the new determined eclipse times with others compiled from the literature, the behavior of their $O – C$ variation was investigated.

Real‐World Pediatric Blinatumomab Administration: Access to Outpatient Care Delivery and Impact of a Hospital‐Dispensed Model

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.
