An extended survey continuing until 2020 couldsurvey an additional 250,000 stars and obtain information on long-period planets from the earlier detectedplanet sample, possibly detecting many solar analogs. ASEPS aims to increase the number of extrasolar planetsby nearly two orders of magnitude (up to 10,000 planets in the 12-year survey using all clear nights). Thisdramatic increase in the number of known planets would allow astronomers to study correlations among thediverse properties of extrasolar planets much more effectively than at present. Additionally, the large numberof planet discoveries will enable the detection of rare planets that may have eluded previous planet searches,as well as transiting planets, and interacting multiple planet systems. In March-June 2006, a single full-scalemulti-object W.M. Keck Exoplanet Tracker (Keck ET) with 60 object capability was commissioned and atrial planet survey of _420 V=8-12 solar type stars has been conducted at Sloan telescope. Since the 2006August engineering run, the instrument performance (throughput, image quality, and Doppler precision) hasbeen substantially improved. Additional stars are being searched for planets. 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102908 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.29 |
