Sub-Saturn Planet MOA-2008-BLG-310Lb: Likely To Be In The Galactic Bulge (2009)

Janczak, Julia, Fukui, A., Dong, Subo, Monard, B., Kozlowski, Szymon, Gould, A., ...

We report the detection of sub-Saturn-mass planet MOA-2008-BLG-310Lb and argue that it is the strongest candidate yet for a bulge planet. Deviations from the single-lens fit are smoothed out by...

Difference imaging photometry of blended gravitational microlensing events with a numerical kernel (2009)

Albrow, M. D., Horne, K., Bramich, D. M., Fouqué, P., Miller, V. R., ...

The numerical kernel approach to difference imaging has been implemented and applied to gravitational microlensing events observed by the PLANET collaboration. The effect of an error in the...

Mass measurement of a single unseen star and planetary detection efficiency for OGLE 2007-BLG-050 (2009)

Batista, V., Dong, Subo, Gould, A., Beaulieu, J. P., Cassan, A., Christie, G. W., ...

We analyze OGLE-2007-BLG-050, a high magnification microlensing event (A ~ 432) whose peak occurred on 2 May, 2007, with pronounced finite-source and parallax effects. We compute planet detection...

New Magellanic Cloud R Coronae Borealis and DY Per type stars from the EROS-2 database: the connection between RCBs, DYPers and ordinary carbon stars (2009)

Tisserand, P., Wood, P. R., Marquette, J. B., Afonso, C., Albert, J. N., Andersen, J., ...

R Coronae Borealis stars (RCB) are a rare type of evolved carbon-rich supergiant stars that are increasingly thought to result from the merger of two white dwarfs, called the Double degenerate...

OGLE-2005-BLG-071Lb, the Most Massive M Dwarf Planetary Companion? (2009)

Dong, Subo, Gould, Andrew, Udalski, Andrzej, Anderson, Jay, Christie, G. W., Gaudi, B. S., ...

We combine all available information to constrain the nature of OGLE-2005-BLG-071Lb, the second planet discovered by microlensing and the first in a high-magnification event. These include...

A systematic fitting scheme for caustic-crossing microlensing events (2009)

Kains, N., Cassan, A., Horne, K., Albrow, M. D., Dieters, S., Fouqué, P., ...

We outline a method for fitting binary-lens caustic-crossing microlensing events based on the alternative model parametrization proposed and detailed by Cassan. As an illustration of our methodology,...

A systematic fitting scheme for caustic-crossing microlensing events (2009)

Kains, N., Cassan, A., Horne, K., Albrow, M. D., Dieters, S., Fouque, P., ...

We outline a method for fitting binary-lens caustic-crossing microlensing events based on the alternative model parameterisation proposed and detailed in Cassan (2008). As an illustration of our...

Albrow, M. D., Horne, K., Bramich, D.M., Fouqué, P., Miller, V.R., ...

The numerical kernel approach to difference imaging has been implemented and applied to gravitational microlensing events observed by the PLANET collaboration. The effect of an error in the...

EROS 2 proper motion survey: a field brown dwarf and an L dwarf companion to LHS 102 (1999)

Goldman, B, Delfosse, X, Forveille, T, Afonso, C, Alard, C, Albert, J N, ...

We report the discovery of two L dwarfs (the new spectral class defined for dwarfs cooler than the M type) in a two-epoch CCD proper motion survey of 413 square degrees, complemented by infrared...
