High-precision polarimetry of nearby stars (d<50 pc) Mapping the interstellar dust and magnetic field inside the Local Bubble

V. Piirola, A. Berdyugin, P. C. Frisch +6

We investigate the linear polarization produced by interstellar dust aligned by the magnetic field in the solar neighborhood (d< 50 pc). We also look for intrinsic effects from cir…

Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016

E. Meza, B. Sicardy, M. Assafin +167

Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…

Mapping the Interstellar Magnetic Field Around the Heliosphere with Polarized Starlight

P. C. Frisch, A. B. Berdyugin, V. Piirola +20

Starlight that becomes linearly polarized by magnetically aligned dust grains provides a viable diagnostic of the interstellar magnetic field (ISMF). A survey is underway to map th…

The structure of Chariklo's rings from stellar occultations

D. Bérard, B. Sicardy, J. I. B. Camargo +79

Two narrow and dense rings (called C1R and C2R) were discovered around the Centaur object (10199) Chariklo during a stellar occultation observed on 2013 June 3. Following this disc…

Pluto's atmosphere from the 29 June 2015 ground-based stellar occultation at the time of the New Horizons flyby

B. Sicardy, J. Talbot, E. Meza +65

We present results from a multi-chord Pluto stellar occultation observed on 29 June 2015 from New Zealand and Australia. This occurred only two weeks before the NASA New Horizons f…

Red noise versus planetary interpretations in the microlensing event OGLE-2013-BLG-446

E. Bachelet, D. M. Bramich, C. Han +98

For all exoplanet candidates, the reliability of a claimed detection needs to be assessed through a careful study of systematic errors in the data to minimize the false positives r…
