WASP or Wide Angle Search for Planets is an international consortium of several academic organisations performing an ultra-wide angle search for exoplanets using transit photometry. The array of robotic telescopes aims to survey the entire sky, simultaneously monitoring many thousands of stars at an apparent visual magnitude from about 7 to 13.{{cite journal | bibcode = 2006PASP..118.1407P | title=The WASP Project and the SuperWASP Cameras | journal=The Publications of the Astronomical Society of the Pacific | volume=118 | pages=1407–1418 | year=2016 |author1=Pollacco, D.

WASP is the detection program composed of the Isaac Newton Group, IAC and six universities from the United Kingdom. The two continuously operating, robotic observatories cover the Northern and Southern Hemisphere, respectively. SuperWASP-North is at Roque de los Muchachos Observatory on the mountain of that name which dominates La Palma in the Canary Islands. WASP-South is at the South African Astronomical Observatory, Sutherland in the arid Roggeveld Mountains of South Africa. These use eight wide-angle cameras that simultaneously monitor the sky for planetary transit events and allow the monitoring of millions of stars simultaneously, enabling the detection of rare transit events.{{cite web |url=http://exoplanetarchive.ipac.caltech.edu/docs/SuperWASPMission.html |title=SuperWASP Survey Information |website=NASA Exoplanet Science Institute |date=5 February 2015}}

Instruments used for follow-up characterization employing doppler spectroscopy to determine the exoplanet's mass include the HARPS spectrograph of ESO's 3.6-metre telescope as well as the Swiss Euler Telescope, both located at La Silla Observatory, Chile.{{cite journal | bibcode = 2010A&A...517L...1Q | title=WASP-8b: a retrograde transiting planet in a multiple system | journal=Astronomy and Astrophysics | volume=517 | pages=L1 | year=2010 |author1=Queloz, D. |author2=Anderson, D.

Equipment

WASP consists of two robotic observatories; SuperWASP-North at Roque de los Muchachos Observatory on the island of La Palma in the Canaries and WASP-South at the South African Astronomical Observatory, South Africa. Each observatory consists of an array of eight Canon 200 mm f1.8 lenses backed by high quality {{resx|2048 x 2048}} science-grade CCDs, the model used is the iKon-L{{Cite web|url=http://wasp-planets.net/technical/|title = Technical|date = 16 December 2013}} manufactured by Andor Technology.{{cite web |url=http://www.andor.com/ |title=Home |website=andor.com}} The telescopes are mounted on an equatorial telescope mount built by Optical Mechanics, Inc.{{cite web |url=http://www.opticalmechanics.com/news/index.html |title=OMI News|access-date=14 February 2009 |url-status=dead |archive-url=https://web.archive.org/web/20071228175159/http://www.opticalmechanics.com/news/index.html |archive-date=28 December 2007 }} The large field of view of the Canon lenses gives each observatory a massive sky coverage of 490 square degrees per pointing.[http://wasp.astro.keele.ac.uk/documents/current%20status%20of%20the%20superwasp%20project.pdf Current status of the SuperWASP project] {{Webarchive|url=https://web.archive.org/web/20160304001733/http://wasp.astro.keele.ac.uk/documents/current%20status%20of%20the%20superwasp%20project.pdf |date=4 March 2016 }}, D. J. Christian et al.

Function

The observatories continuously monitor the sky, taking a set of images approximately once per minute, gathering up to 100 gigabytes of data per night. By using the transit method, data collected from WASP can be used to measure the brightness of each star in each image, and small dips in brightness caused by large planets passing in front of their parent stars can be searched for.

One of the main purpose of WASP was to revolutionize the understanding of planet formation, paving the way for future space missions searching for 'Earth'-like worlds.

Structure

WASP is operated by a consortium of academic institutions which include:

On 26 September 2006, the team reported the discovery of two extrasolar planets: WASP-1b (orbiting at 0.038 AU (6 million km) from star once every 2.5 days) and WASP-2b (orbiting three-quarters that radius once every 2 days).{{Cite journal |arxiv = astro-ph/0609688|bibcode = 2007MNRAS.375..951C|title = WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE|journal = Monthly Notices of the Royal Astronomical Society|volume = 375|issue = 3|pages = 951–957|last1 = Collier Cameron|first1 = A|last2 = Bouchy|first2 = F|last3 = Hébrard|first3 = G|last4 = Maxted|first4 = P|last5 = Pollacco|first5 = D|last6 = Pont|first6 = F|last7 = Skillen|first7 = I|last8 = Smalley|first8 = B|last9 = Street|first9 = R.

On 31 October 2007, the team reported the discovery of three extrasolar planets: WASP-3b, WASP-4b and WASP-5b. All three planets are similar to Jovian mass and are so close to their respective stars that their orbital periods are all less than two days. These are among the shortest orbital periods discovered. The surface temperatures of the planets should be more than 2000 degrees Celsius, owing to their short distances from their respective stars. The WASP{{Non breaking hyphen}}4b and WASP-5b are the first planets discovered by the cameras and researchers in South Africa. WASP-3b is the third planet discovered by the equivalent in La Palma.

In August 2009, the discovery of WASP-17b was announced, believed to be the first planet ever discovered to orbit in the opposite direction to the spin of its star, WASP-17.
