2MASS, SDSS and BVRI photometry for 825 stars (Bilir+, 2008)
We present colour transformations for the conversion of the 2MASS photometric system to the Johnson-Cousins UBVRI system and further into the SDSS ugriz system...
2MASS/SDSS data for 806 ultracool dwarfs (Zhang+, 2010)
SDSS (II/294), 2MASS (II/246) and UKIDSS (II/304) photometry of 806 ultra-cool dwarfs. Proper motions are found by dividing the difference between the 2MASS and...
3 - 5 micron Photometry of 500 - 800 K Brown Dwarfs
We request 9.1hrs to obtain IRAC photometry of 11 cold brown dwarfs. The observations will complete the dataset of near-infrared spectroscopy and 1-5um...
We report the discovery of 3 previously unseen X-ray point sources detected in a 5ks Chandra/ACIS observation starting on 2007-07-31.14 UT as part of our...
3-D Study of the Nebula Around the Symbiotic Mira He2-147
The expansion in the plane of the sky of the nebula around the symbiotic nova He2-147 has been resolved by means of two HST WFPC2 [NII] images taken 3 years...
3.5 years of observing exoplanet day sides with CHEOPS
Characterising Exoplanets Satellite (CHEOPS) is the first ESA exoplanet space mission. The satellite carries a 30cm telescope, optimised to deliver exquisite...
30 years of dust outbreaks over the Canary Islands from astronomical telescopes
Telescopes on the North Atlantic Islands of La Palma and Tenerife, in the Canary Islands Archipelago have recorded optical extinction for approximately 30 years...
