Discovery of the neutron star spin and orbital period from the Be/X-ray binary IGR J05414-6858 in the LMC
Discovery neutron star spin orbital the Be/X-ray binary IGR J05414-6858 the LMC
2012/2/22
The number of known Be/X-ray binaries in the Large Magellanic Cloud is small compared to the observed population of the Galaxy or the Small Magellanic Cloud. The discovery of a system in outburst prov...
Period Change Similarities among the RR Lyrae Variables in Oosterhoff I and Oosterhoff II Globular Systems
Period Change Similarities among RR Lyrae Variables
2010/11/30
We present period change rates (dP/dt) for 42 RR Lyrae variables in the globular cluster IC$\,$4499. Despite clear evidence of these period increases or decreases, the observed period change rates are...
Orbital Period Determinations for Four SMC Be/X-ray Binaries
Orbital Period Determinations SMC Be/X-ray Binaries
2010/11/30
We present an optical and X-ray study of four Be/X-ray binaries located in the Small Magellanic Cloud (SMC). OGLE I-band data of up to 11 years of semi-continuous monitoring has been analysed for SMC ...

Binaries are not always neatly aligned. Previous observations of the DI Her system showed that the spin axes of both stars are highly inclined with respect to one another and the orbital axis. Here we...
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
stars general — oscillations individual(KPD1930+2752)
2010/11/1
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellip-soidal variable with a known binary period just over two hours. The companion is most likely a white dwarf and the ...
Long-term photometric monitoring of Messier 5 variables: I. Period changes of RR Lyrae stars
Solar and Stellar Astrophysics (astro-ph.SR)
2010/10/5
The period changes of 86 M5 RR Lyrae stars have been investigated on a one-hundred-year time base. The published observations have been supplemented by archival Asiago, Konkoly and Las Campanas photog...
Transit timing variations in eccentric hierarchical triple exoplanetary systems. I. Perturbations on the time-scale of the orbital period of the perturber
Earth and Planetary Astrophysics (astro-ph.EP) Solar and Stellar Astrophysics (astro-ph.SR)
2010/10/5
We study the long-term time-scale (i.e. period comaprable to the orbital period of the outer perturber object) transit timing variations in transiting exoplanetary systems which contain a further, mor...
WASP-38b: A Transiting Exoplanet in an Eccentric, 6.87d Period Orbit
Earth and Planetary Astrophysics (astro-ph.EP)
2010/10/5
We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2455335.92050 +/- 0.00074 (HJD) and the transit duration is 4.663 hours. W...
