A spectroscopic study of a large sample of L/T transition brown dwarfs
(University of Hertfordshire, 2014-09-25)
In this thesis I present the spectroscopic analysis of a large sample of L and T dwarfs,
in order to constrain the sub-stellar initial mass function and formation history. The
main points I tried to address are the ...
Studies of Metal Poor T Dwarfs in UKIDSS
(University of Hertfordshire, 2013-07-31)
I have used blue near-infrared colours to select a group of UKIDSS T dwarfs with spectral
types later than T4. From amongst these I identify two kinematic halo T-dwarf candi-
dates. Blue near-infrared colours have been ...
