Exoplanet HAT-P-25b in Ari
Dear group,
Finally some clear skies following a month of incessant clouds and
rains.
With the moon at a phase of 64% at the onset of darkness, there was
little room for DSO work. To this end, back to photometry involving
HAT-P-25b in Aries and whose discovery was announced in Aug/2010.
It is a lesser density hot-Jupiter and whose host star is one of the
dimmer exoplanet host stars discovered to date by a ground-based
exoplanet hunting team.
HAT-P-25b requires 3.65 days to completely orbit its G5 dwarf host
star.
With the moon approximately 20 degrees further west, I had serious
reservations about getting a decent result and especially given the
13.19 magnitude of the host star. However, all is well that ends well.
Anthony.
