Veloce

 
 

Veloce Rosso was funded by a LIEF 2015 grant awarded to a consortium led by UNSW and including ANU, USQ, AAO, Sydney and Macquarie. Thanks to additional contributions by UNSW and USQ funds are now up to $1.65m!


The Veloce project aims to equip the Anglo-Australian Telescope with a compact ultra-stabilised spectrograph, able to obtain Doppler velocities for Sun-like and M-dwarf stars at sub-m/s precision. It will provide essentially all the functionality delivered by the current UCLES spectrograph, with a larger collecting area from the sky, large simultaneous wavelength coverage, higher resolution and better throughput.


Veloce Rosso's key features are

  1. IFU Fibre-feed as demonstrated by the CYCLOPS Facilities

  2. Compact asymmetric, white-pupil design, including pressure and temperature stabilisation.

  3. Wavelength coverage from ~ 600-950nm at R~80,000

  4. Simultaneous calibration utilising a pulsed-laser-comb which delivers a bright, stable calibration source with thousands of lines at the few cm/s level.


Funded Upgrades

  1. Successful LIEF grant in 2016 has funded (A$1.14m) the purchase of a laser-comb covering 450-950nm from Menlo Systems GmbH. This will deliver exquisite calibration of the spectrograph across the whole Veloce Rosso range.


Upgrades for Veloce Rosso planned for the future are

  1. Implement Veloce Verde  - an additional camera delivering data from Hbeta to Halpha at R~80,000.

  2. Implement Veloce Azzurre  - an final camera delivering data from 350-450nm at R~40,000.

  3. A "faint object" fibre feed and science-quality slit-viewing camera.

  4. Implement a spectro-polarimetry module at the AAT's Cassegrain focus.

  5. Implement fibre feeds to Auxiliary Telescopes external to the AAT, allowing use of Veloce 365 days a year for bright targets.
