When Nature Tries to Trick Us
Henri M. J. Boffin, David Jones, Roger Wesson +7
Bipolar planetary nebulae (PNe) are thought to result from binary star interactions and, indeed, tens of binary central stars of PNe have been found, in particular using photometri…
BANYAN. IX. The Initial Mass Function and Planetary-Mass Object Space Density of the TW Hya Association
Jonathan Gagné, Jacqueline K. Faherty, Eric E. Mamajek +15
A determination of the initial mass function (IMF) of the current, incomplete census of the 10 Myr-old TW Hya association (TWA) is presented. This census is built from a literature…
BANYAN. VI. Discovery of a companion at the brown dwarf/planet-mass limit to a Tucana-Horologium M dwarf
Étienne Artigau, Jonathan Gagné, Jacqueline Faherty +5
We report the discovery of a substellar companion to 2MASS J02192210-3925225, a young M6 candidate member of the Tucana-Horologium association (30 - 40 Myr). This L4 compan…
The Closest Known Flyby of a Star to the Solar System
Eric E. Mamajek, Scott A. Barenfeld, Valentin D. Ivanov +4
Passing stars can perturb the Oort Cloud, triggering comet showers and potentially extinction events on Earth. We combine velocity measurements for the recently discovered, nearby,…
Discovery of a new Y dwarf: WISE J030449.03-270508.3
D. J. Pinfield, M. Gromadzki, S. K. Leggett +21
We present a new Y dwarf, WISE J030449.03-270508.3, confirmed from a candidate sample designed to pick out low temperature objects from the WISE database. The new object is typed Y…
Clues on the Galactic evolution of sulphur from star clusters
E. Caffau, L. Monaco, M. Spite +6
(Abridged) The abundances of alpha-elements are a powerful diagnostic of the star formation history and chemical evolution of a galaxy. Sulphur, being moderately volatile, can be r…
