V346 Nor: the post-outburst life of a peculiar young eruptive star
(2020-02-03)
FU Orionis-type objects (FUors) are young low-mass stars undergoing powerful accretion outbursts. The increased accretion is often accompanied by collimated jets and energetic, large-scale molecular outflows. The extra ...
Extremely metal-poor stars from the cosmic dawn in the bulge of the Milky Way
(2015-11-26)
The first stars are predicted to have formed within 200 million years after the Big Bang, initiating the cosmic dawn. A true first star has not yet been discovered, although stars with tiny amounts of elements heavier than ...
MOA-2011-BLG-262Lb : A sub-earth-mass moon orbiting a gas giant primary or a high velocity planetary system in the galactic bulge
(2014-04-20)
We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M host ∼ 4 Jupiter masses hosting a sub-Earth mass moon. The argument for an exomoon ...
The influence of binarity on dust obscuration events in the planetary nebula M 2-29 and its analogues
(2011)
The central star of the planetary nebula (CSPN) M 2-29 shows an extraordinary R Coronae Borealis-like fading event in its optical lightcurve. The only other CSPN to show these events are CPD−56◦8032 (Hen 3-1333) and V651 ...
The VMC survey II : A multi-wavelength study of LMC planetary nebulae and their mimics
(2011)
The VISTA Magellanic Cloud (VMC) survey is assembling a deep, multi-epoch atlas of Y JKs photometry across the Magellanic Clouds. Prior to the VMC survey only the brightest Magellanic Cloud PNe (MCPNe) were accessible at ...
