Searching for intermediate-mass black holes in globular clusters with gravitational microlensing
N. Kains, D. M. Bramich, K. C. Sahu +1
We discuss the potential of the gravitational microlensing method as a unique tool to detect unambiguous signals caused by intermediate-mass black holes in globular clusters. We se…
RR Lyrae stars and the horizontal branch of NGC 5904 (M5)
A. Arellano Ferro, A. Luna, D. M. Bramich +3
We report the distance and [Fe/H] value for the globular cluster NGC 5904 (M5) derived from the Fourier decomposition of the light curves of selected RRab and RRc stars. The aim in…
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…
Spitzer Observations of OGLE-2015-BLG-1212 Reveal a New Path to Breaking Strong Microlens Degeneracies
V. Bozza, Y. Shvartzvald, A. Udalski +98
Spitzer microlensing parallax observations of OGLE-2015-BLG-1212 decisively breaks a degeneracy between planetary and binary solutions that is somewhat ambiguous when only ground-b…
Revisiting the variable star population in NGC~6229 and the structure of the Horizontal Branch
A. Arellano Ferro, P. E. Mancera Piña, D. M. Bramich +4
We report an analysis of new and CCD time-series photometry of the distant globular cluster NGC 6229. The principal aims were to explore the field of the cluster in search…
New variables in M5 (NGC 5904) and some identification corrections
A. Arellano Ferro, D. M. Bramich, S. Giridhar +2
We report twelve variables not previously detected in the globular cluster M5 (NGC 5904); one SX Phe and eleven semi-regular variables (SR). Their identifications, equatorial coord…
