Dust from Comet 209P/LINEAR during its 2014 Return: Parent Body of a New Meteor Shower, the May Camelopardalids
Masateru Ishiguro, Daisuke Kuroda, Hidekazu Hanayama +29
We report a new observation of the Jupiter-family comet 209P/LINEAR during its 2014 return. The comet is recognized as a dust source of a new meteor shower, the May Camelopardalids…
The HARPS search for southern extra-solar planets XXXV. Planetary systems and stellar activity of the M dwarfs GJ 3293, GJ 3341, and GJ 3543
N. Astudillo-Defru, X. Bonfils, X. Delfosse +13
Context. Planetary companions of a fixed mass induce larger amplitude reflex motions around lower-mass stars, which helps make M dwarfs excellent targets for extra-solar planet sea…
High-precision photometry by telescope defocussing. VII. The ultra-short period planet WASP-103
John Southworth, L. Mancini, S. Ciceri +25
We present 17 transit light curves of the ultra-short period planetary system WASP-103, a strong candidate for the detection of tidally-induced orbital decay. We use these to estab…
The small binary asteroid (939) Isberga
B. Carry, A. Matter, P. Scheirich +29
In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic quantity. We aim here to characterize the surface composition, mu…
Pathway to the Galactic Distribution of Planets: Combined Spitzer and Ground-Based Microlens Parallax Measurements of 21 Single-Lens Events
S. Calchi Novati, A. Gould, A. Udalski +82
We present microlens parallax measurements for 21 (apparently) isolated lenses observed toward the Galactic bulge that were imaged simultaneously from Earth and Spitzer, which was…
L'-band AGPM vector vortex coronagraph's first light on LBTI/LMIRCam
D. Defrère, O. Absil, P. Hinz +20
We present the first observations obtained with the L'-band AGPM vortex coronagraph recently installed on LBTI/LMIRCam. The AGPM (Annular Groove Phase Mask) is a vector vortex coro…
