Exoplanet WASP-3b in Lyra
Dear group,
One of the latest exoplanet announcements involves WASP-3b in Lyra and which requires 160 minutes to transit its parent star and at a depth of 11.4 mmag. Given its proximity to its parent star and relatively high mass (1.76x that of Jupiter), WASP-3b is one of the largest and hottest Jupiter-like finds so far. The ten-day old moon was a problem during the four-hr session last night and thankfully my Baader Infrared Pass filter did a wonderful job in helping improve contrast while minimizing the mitigating effects of the lunar light (pollution). The results from last night's session are available at http://www.perseus.gr/Astro-Photomet...3-20080613.htm . All systems are go for Sunday evening and a visit to another foreign world but this time in Ursa Major. Clear skies! Anthony. |

Secondly I was wondering if it would be any trouble to help me understand something about your results; - What does the word 'depth' refer to? I'm professing my lack of total knowledge about everything, everywhere, all the time. TBerk 44.3 hour orbit, twice as big as Jupiter. Wow. |

Brings a smile to me on another night of severe storms in Iowa. Iowa crested last night, Cedar is falling. CR is a disaster. We may escape here. Will know by Wednesday |

Exoplanet WASP-3b in Lyra
Thanks to everyone for the kind words. I have a lot of planned work
for the latter part of June and there will be lots more results to share with everyone. With respect to the friend asking about depth, it is the amount by which the magnitude of the host star drops when the exoplanet is transitting its disk and thereby blocking some of the light. For example, a depth of "12 mmag" means that the magnitude of the parent star will drop by 0.012 magnitudes during transit (ex. from 10.000 to 10.012). I have captured eight exoplanets so far with depths varying from 6.2 mmag (ie. 0.0062 magnitudes) to 33 mmag (0.033 magnitudes) and which you can see at http://www.perseus.gr/Astro-Photometry.htm ... I should have 20 total exoplanets in the bag by the end of July. Clear skies to everyone! Anthony.
