Expenditures by Nonmotorized Recreationists in the Adirondack Park

Hikers, paddlers, and cyclists at six sites in the central and northern Adirondack Park were interviewed about their outdoor recreation activities and expenditures. Interviews were conducted on 46 randomly-selected half-days for a 4% sample of time periods between late May and late August, 2000. From interview results, I estimate that 6,075 parties or 17,750 persons entered the back country at these points during the summer. Parties were in the Park an average of 3.6 days, during which time each person spent an average of $25-$42 locally for services such as gas, food, lodging, shopping and admission fees. Many parties were also carrying gear purchased at some time in the Adirondack Park, averaging $75-$115 worth of gear per person. These results compare well with those collected in Maine and other New York State parks. I estimate that all visitors to the six sites spent one to two million dollars in services for the summer, two to four million dollars in services for the year

Planet Hunters X: Searching for Nearby Neighbors of 75 Planet and Eclipsing Binary Candidates from the K2 Kepler Extended Mission

We present high-resolution observations of a sample of 75 K2 targets from Campaigns 1-3 using speckle interferometry on the Southern Astrophysical Research (SOAR) telescope and adaptive optics (AO) imaging at the Keck II telescope. The median SOAR $I$-band and Keck $K_s$-band detection limits at 1" were $\Delta m_{I}=4.4$~mag and $\Delta m_{K_s}=6.1$~mag, respectively. This sample includes 37 stars likely to host planets, 32 targets likely to be eclipsing binaries (EBs), and 6 other targets previously labeled as likely planetary false positives. We find nine likely physically bound companion stars within 3" of three candidate transiting exoplanet host stars and six likely EBs. Six of the nine detected companions are new discoveries; one of the six, EPIC 206061524, is associated with a planet candidate. Among the EB candidates, companions were only found near the shortest period ones ($P<3$ days), which is in line with previous results showing high multiplicity near short-period binary stars. This high-resolution data, including both the detected companions and the limits on potential unseen companions, will be useful in future planet vetting and stellar multiplicity rate studies for planets and binaries.Comment: Accepted in A
