MINERVA-Australis Time Through NN-Explore

As part of the NN-EXPLORE program, NASA has entered into a partnership with the MINERVA-Australis consortium. Starting in 2020B, 300 hours of shared-risk observing time per semster with the facility on MINERVA-Australis are available to researchers based at US institutions. MINERVA-Australis is a dedicated exoplanet observatory operated by the University of Southern Queensland (USQ) in Queensland, Australia. The MINERVA-Australis facility is suitable for observation programs requiring precision radial velocities such as individual measurements to constrain orbits and masses, RM-effect, or Doppler tomography, precision photometric observations such as transit observations, and spectroscopic stellar characterization.

The facility is located at USQ's Mt. Kent Observatory, and saw first light in 2018; commissioning of the facility was completed in mid-2019. MINERVA-Australis consists of 4 (0.7m) PlaneWave CDK700 telescopes; these telescopes have two ports, allowing each to be used for either spectroscopic or photometric observations.

A summary of the facility and its capabilities can be found in the commissioning paper by Addison et al. 2019. The photometric channel is capable of milli-magnitude precision and the light from four telescopes can be combined onto one R=75,000 echelle spectrograph for radial velocity precisions of 1 -10 m/s depending on the target brightness. While the telescopes can be operated individually, they are intended to be operated as an array.

Restrictions of the Call

NASA has made available to researchers based at US institutions, 300 hours on the Minerva-Australis facility per semester. The time is intended for exoplanet research, primarily of TESS targets but other exoplanet science will be considered. Proposed observing time will be allocated in hours and must include all science and calibration observations necessary to accomplish the science. More information can be requested by contacting David Ciardi at NExScI or Rob Wittenmyer at USQ.

As MINERVA-Australis is a scientific consortium, proposers must abide by the following restrictions:

The community-proposed targets will be restricted to TOIs from TESS Sectors 1 - 13 or to non-TOI targets at the time of the proposal submission.

  • The MINERVA-Australis has listed a set of "Collaboration Targets," which are a set of targets that the collaboration is observing (see LIST HERE ). "Collaboration Targets" can be proposed for observation through the NASA time if the proposal principal investigator forms a collaboration with the appropriate MINERVA-Australis collaboration or the proposer and the MINERVA-Australis collaboration member come to a mutual agreement regarding the proposed observations.
  • Observations will be made, on behalf of the NASA observers, in queue-mode by the MINERVA-Australis team.
  • The MINERVA-Australis team will deliver the proposer's raw data, 1D extracted spectra, and radial velocities (if desired by the proposer).
  • Data obtained for US community observers will be archived at NExScI, through the ExoFOP service. Archived data will have the option to have a maximum 12-month proprietary period or of making the data public with no proprietary period.
  • Any publications arising from the use of NASA time on MINERVA-Australis are subject to the main MINERVA-Australis publication policy regarding the inclusion of the listed Architects and Builders [to be provided by the Collaboration] and should acknowledge the NN-EXPLORE Program [see below].

Proposing for the Call

Proposals should be submitted to the NN-Explore Program through the NOIRLab proposal process. Information about the current NOIRLab call can be found at the NOIRLab proposal pages.

Acknowledgments for Selected Programs
