Preface The idea for organising a conference to celebrate Ant’s contributions to star formationhasbeenfloatingaroundforafewyears.Weconsideredvariouslocations andwefinallychoseCreteinspiredbyAnt’sdeclaredlovefortheplace.Themeeting tookplacenearChaniaattheOrthodoxAcademyofCrete,aconferencecentrenext toaseventeenth-centurymonastery.Itwasattendedbyaround120participantsfrom allovertheworld,manyofwhichhaveinteractedwithAntinthepast. The conference theme was chosen to reflect Ant’s interests in star formation andcomputationalastrophysics.Wecoveredmanytopics:low-massstarformation, young circumstellar discs, computational methods, triggered star formation, the stellar initial mass function, high-mass star formation, and stellar clusters. Each chapter starts with a review contribution that is followed by papers focusing on recenttheoreticalandobservationalwork. WewouldliketothankthemembersoftheSOC(PhilippeAndré,MatthewBate, IanBonnell,CathieClarke,PatrickHennebelle,Shu-ichiroInutsuka,RalfKlessen, PavelKroupa,MarkKrumholz,MarkMcCaughrean,JanPalous,HansZinnecker) and LOC (Annabel Cartwright Thomas Bisbas, David Hubber, Spyros Kitsionas, SteffiWalch,RichardWünsch)fortheirenthusiasmtocontributetothemeeting. We also thank Spyros Kitsionas for his help with the conference proceedings, DavidNutterfortheconferencephoto,SamanthaEmmotandtheCardiffUniversity Conference Centre, and Richard Frewin for his support with the conference webpage. Finally, we would like to thank Emmanuela Larentzakis and the staff at theOrthodoxAcademyofCretefortheirhelpinorganisingawonderfulconference. It was amazing to hear and discuss new ideas, and argue over older ideas in a relaxing environment overlooking the Aegean sea. We hope that new theories and observations using new facilities will soon draw a more complete picture of star formation.
