Unveiling the nature of IGR J17177-3656 with X-ray, NIR and Radio observations
accretion accretion disks – X-rays binaries – binaries
2011/8/24
We report on the first broad-band (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011, March 22, about two we...
An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
globular clusters early-type galaxies II

Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fraction of intermediate-...
High Mass X-ray Binaries in the NIR : Orbital solutions of two highly obscured systems
High Mass X-ray Binaries；the NIR
2011/1/13
The maximum mass of a neutron star (NS) is poorly defined. Theoretical attempts to define this mass have thus far been unsuccessful. Observational results currently provide the only means of narrowing...
The Principal Parameters of Unstudied Open Clusters with NIR Observations
Principal Parameters of Unstudied Open Clusters NIR Observations
2010/11/15
We studied the principal parameters of some previously unstudied open star clusters using the JHK Near-IR photometry (2MASS survey). These clusters have been selected from the updated Catalogs of Dais...

The combination of optical and near-infrared (NIR) colours has the potential to break the age/metallicity degeneracy and offers a better metallicity sensitivity than optical colours alone.
