Gliese 436 is an M dwarf with a mass of 0.45 Msun and hosts the extrasolar planet GL 436b [3, 6, 7, 2], which is currently the least massive transiting planet with a mass of ~23.17…
New Observations and a Possible Detection of Parameter Variations in the Transits of Gliese 436b
Jeffrey L. Coughlin, Guy S. Stringfellow, Andrew C. Becker +3
We present ground-based observations of the transiting Neptune-mass planet Gl 436b obtained with the 3.5-meter telescope at Apache Point Observatory and other supporting telescopes…
Long-term Photometric Analysis of the Active W UMa-type System TU Bootis
Jeffrey L. Coughlin, Horace A. Dale, Richard M. Williamon
We present multi-color light curves for the W UMa-type eclipsing binary TU Boo for two epochs separated by 22 years. An analysis of the O-C diagram indicates the earlier observatio…
