The Rocks, Rings and Rubble Workshop in Leiden in September 2016.

We are coordinating and listing the observing campaigns for monitoring beta Pictoris during the Hill sphere transit in 2017.

Please email me with details if you are planning observations of beta Pictoris during 2016 to 2018.

Photometric Monitoring

bRing

PI: M. Kenworthy at Leiden Observatory, the Netherlands Co-I's: E. Mamajek, R. Stuik, S. Mellon, S. Crawford

The beta Pic b ring camera (bRing) consists of two telephoto lenses with support computers, covering the path of beta Pic across the Southern hemisphere. The design builds on the heritage gained in Leiden from the MASCARA all sky surveys.

To get longitudinal coverage, two separate bRing cameras are being built (one by Leiden Observatory for South Africa and one by University of Rochester for Australia) and the data will be combined with MASCARA South (late 2016) to provide redundant coverage.

The expected photometric precision is 0.5% with 5 minutes of data.

Dates: bRing South Africa is now online and taking data (Feb 2017). Australia expected in Summer 2017.

BRITE

PI: K. Zwintz, University of Innsbruck, Austria

The BRITE satellites are a constellation of CubeSats that monitor bright stars across the celestial sphere. An observing campaign will provide millimagnitude photometry in Q1 of 2017.

Observations currently underway and will email a trigger if sudden changes in photometry are noted.

Dates: November 2016 to April 2017 and Late 2017.

PICSAT

PI: S. Lacour, Paris.

PICSAT is a dedicated CubeSat that will monitor beta Pictoris using a single mode fibre.

Dates: Expected launch in Q2 of 2017.

HST

PI: J. Wang, Berkeley.

Probing the young circumplanetary environment of a directly-imaged exoplanet through a rare transit event - Cycle 24 proposal (accepted).

6 orbits of WFC3 in spatial scanning mode.

Antarctic Cameras

ASTEP400

Science Contact Tristan Guillot, Observatoire de la Cote d'Azur, Institut polaire francais Paul-Emile Victor (IPEV)

ASTEP400 at Dome C will observe beta Pic with an i' filter continuously May - August 2017. This is a 40 cm telescope with a 4Kx4K detector, 0.93 arcsec pixels and a one degree field of view. Readout time is 20 seconds. Automated photometry in various apertures is performed on-site and light curves sent to Nice, France.

AST3-2

Science Contact Lifan Wang, Texas A&M, Polar Research Institute of China

AST3-2 is one of three 68 cm telescopes at Dome A that will observe beta Pic with a g filter May - August 2017. This has a 5Kx10K detector, 1 arcsec pixels and a 4.3 sq degree field of view. Light curves should be available within a few minutes.

Spectroscopic Monitoring

BRITE

PI: K. Zwintz, University of Innsbruck, Austria

The BRITE satellites are a constellation of CubeSats that monitor bright stars across the celestial sphere. An observing campaign will provide millimagnitude photometry in Q1 of 2017.

Dates: November 2016 to April 2017.

SALT-HRS

PI: Blaine Lomberg, Southern African Astronomical Observatory “Spectroscopic Observations of the Hill Sphere Transit in star Beta Pictoris”

Monitoring Beta Pic with a monthly cadence to be increased to a weekly cadence a month prior to the predicted start of the Hill Sphere transit.

Provisional: If the Hill Sphere even occurs, we will request further time as DDT request as recommended

Dates:

  • Baseline Nov 3, 2016 - Feb 22, 2017
  • 1st Epoch Mar 1, 2017 - April 30, 2017
  • 2nd Epoch Aug 7, 2017 - Oct 30, 2017
