Parallaxes for L-type Brown Dwarfs
Honours Project Supervisor:
Professor Chris Tinney


I have in hand about 4 years worth of data acquired at the AAT with the WFI camera of a sample of nearby L-dwarfs selected from the 2MASS all-sky survey. These data will be processed and subject to an astrometric analysis that should lead to the measurement of trigonometric distances to a large subset of the objects observed. In addition the same data will be used to provide improved photometric flux measurements for these brown dwarfs in the Gunn i and z passbands.



Discovering Wide-separation Companions to the Coolest Brown Dwarfs
Honours Project Supervisor:
Professor Chris Tinney


Over the last 2 years, astronomers in the Exoplanetary Science at UNSW group led by Prof Chris Tinney have been studying a sample of the coolest Y-type brown dwarfs (objects with temperatures as cool as 400K) to measure their distances via trigonometric parallax.

In this project you will be using that data (acquired on the Magellan 6.5m telescope in Chile) to look for other objects in the field of view of the camera that share a common motion across the sky with the planetary-mass brown dwarfs we are studying. You will be working on image analysis and data processing, so skills in data handling and programming/scripting will be useful.
