cds-question@unistra.fropen-star-clustersproper-motionsstellar-spectral-typesBecause of its proximity to the Galactic plane, reliable identification of members of the {alpha} Persei cluster is often problematic. Based primarily on membership evaluations contained in six published papers, we constructed a mostly complete list of high-fidelity members of spectral type G and earlier that lie within 3 arc degrees of the cluster center. {alpha} Persei was the one nearby, rich, young open cluster not surveyed with the Spitzer Space Telescope. We examined the first and final data releases of the Wide-field Infrared Survey Explorer (WISE) and found 11, or perhaps 12, {alpha} Per cluster members that have excess mid-infrared emission above the stellar photosphere attributable to an orbiting dusty debris disk. The most unusual of these is V488 Per, a K-type star with an excess IR luminosity 16% (or more) of the stellar luminosity; this is a larger excess fraction than that of any other known dusty main-sequence star. Much of the dust that orbits V488 Per is at a temperature of ~800 K; if these grains radiate like blackbodies, then they lie only ~0.06 AU from the star. The dust is probably the aftermath of a collision of two planetary embryos or planets with small semimajor axes; such orbital radii are similar to those of many of the transiting planets discovered by the Kepler satellite.2012ApJ...752...58Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/752/58CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/68 : Positions and Proper Motions in alpha Per cluster (Fresneau, 1980)I/315 : UCAC3 Catalogue (Zacharias+ 2009)I/259 : The Tycho-2 Catalogue (Hog+ 2000)V/80 : Low-Mass Stars' Membership in Alpha Persei Cluster (Prosser 1992)J/MNRAS/426/3403 : UKIDSS-GCS {alpha} Per members (Lodieu+, 2012)J/A+A/488/409 : Radial velocities of {alpha} Per stars (Mermilliod+, 2008)J/AJ/131/2967 : {alpha} Persei open cluster members (Makarov+, 2006)J/PASP/118/636 : Alpha Per HR spectral atlas at 3810-8100{AA} (Lee+, 2006)J/A+A/416/125 : RI photometry in alpha Per and Pleiades (Deacon+, 2004)J/AJ/123/1570 : alpha Persei and Praesepe Clusters (Patience+, 2002)J/A+A/395/813 : Alpha Per faint stars photometry (Barrado y Navascues+, 2002)J/A+A/345/471 : Memberships of open clusters (Robichon+, 1999)J/AN/319/215 : Alpha Per cluster low-mass members.
