Binaries wider than about 100AU are indistinguishable from single stars in all aspects. Binaries in the 5-100AU range, on the other hand, are associated with shorter lived but (at least in some cases) equally massive disks. Furthermore, they form planetesimals and mature planetary systems at a similar rate as wider binaries and single stars, albeit with the peculiarity that they predominantly produce high-mass planets. I posit that the location of a stellar companion influences the relative importance of the core accretion and disk fragmentation planet formation processes, with the latter mechanism being predominant in binaries tighter than 100AU.2010ApJ...709L.114Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/709/L114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/696/L84 : Primordial circumstellar disks in binary systems (Cieza+,J/ApJ/703/1964 : Spectra of three nearby star-forming regions (Furlan+, 2009)J/PASJ/60/209 : Faint companions around YSOs in TMC (Itoh+, 2008)J/ApJS/179/451 : Predicted IR excesses for protoplanetary disks (Kenyon+, 2008)J/ApJ/671/1800 : SCUBA observations of {rho} Oph cloud (Andrews+, 2007)J/ApJ/647/1180 : Infrared photometry of Taurus SFR (Luhman+, 2006)J/ApJ/636/932 : Mid-infrared survey of T Tauri stars (McCabe+, 2006)J/A+A/372/173 : ISOCAM observations of the rho Ophiuchi cloud (Bontemps+,J/ApJS/101/117 : UBVRIJHKLMNQ photometry in Taurus-Auriga (Kenyon+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/709/L114https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/709/L114http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/709/L114https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/709/L114https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/709/L114http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/709/L114GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/709/L114/table1 (Sample of Taurus and Ophiuchus protoplanetary disks considered in this study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/709/L114/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/709/L114/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/709/L114/table1?GETtext/xml+votable180.050000true64.631612528.2829250.0055555555555555566/342 377 473 478 1031 1039 1040 1048 1050 1052 1054 1073 1074 1075 1080 1082 1111 1123 1124 1136 1154 1159 1168 1199 23543 23548 23549 23551 24203 42970 42976 42980 42981 42983 42992 43000 443791.528037907652962e-22 1.528037907652962e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/709/L114?format=asciiRadiodefaultJ/ApJ/709/L114/table1Sample of Taurus and Ophiuchus protoplanetary disks considered in this studySimbadNameSimbad column added by the CDSmeta.idcharf_d?[f] Presence of inner disk from SED (2)meta.codecharrecnoRecord number assigned by the VizieR team.
