OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?
M. Dominik, E. Bachelet, V. Bozza +40
(abridged) Using the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale ~ 300 d, we present a methodology for identifying the na…
MiNDSTEp differential photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756: Microlensing and a new time delay
E. Giannini, R. W. Schmidt, J. Wambsganß +52
We present V and R photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756. The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope…
High-resolution Imaging of Transiting Extrasolar Planetary systems (HITEP). I. Lucky imaging observations of 101 systems in the southern hemisphere
D. F. Evans, J. Southworth, P. F. L. Maxted +33
(abridged) Context. Wide binaries are a potential pathway for the formation of hot Jupiters. The binary fraction among host stars is an important discriminator between competing fo…
Exploring the crowded central region of 10 Galactic globular clusters using EMCCDs. Variable star searches and new discoveries
R. Figuera Jaimes, D. M. Bramich, J. Skottfelt +31
Obtain time-series photometry of the very crowded central regions of Galactic globular clusters with better angular resolution than previously achieved with conventional CCDs on gr…
High-precision photometry by telescope defocussing. VIII. WASP-22, WASP-41, WASP-42 and WASP-55
John Southworth, J. Tregloan-Reed, M. I. Andersen +47
We present 13 high-precision and four additional light curves of four bright southern-hemisphere transiting planetary systems: WASP-22, WASP-41, WASP-42 and WASP-55. In the cases o…
Rotation periods and astrometric motions of the Luhman 16AB brown dwarfs by high-resolution lucky-imaging monitoring
L. Mancini, P. Giacobbe, S. P. Littlefair +33
Context. Photometric monitoring of the variability of brown dwarfs can provide useful information about the structure of clouds in their cold atmospheres. The brown-dwarf binary sy…
