LSPM J0207+3331是在2018年10月由[[公民科學]]計畫{{link-en|後院世界|Backyard Worlds}}（Backyard Worlds）的參與者發現<ref name="blogpost20190219">{{cite web|url=https://blog.backyardworlds.org/2019/02/19/the-crystal-ball-white-dwarf/|title=The Crystal Ball White Dwarf|date=19 February 2019|website=Blog.backyardworlds.org|accessdate=22 February 2019|archive-date=2020-10-26|archive-url=https://web.archive.org/web/20201026151840/https://blog.backyardworlds.org/2019/02/19/the-crystal-ball-white-dwarf/|dead-url=no}}</ref><ref>{{cite web|url=https://svs.gsfc.nasa.gov/13147|title=Volunteer Discovers Record-Setting White Dwarf Star|date=19 February 2019|website=NASA.gov|accessdate=22 February 2019|archive-date=2020-10-27|archive-url=https://web.archive.org/web/20201027202004/https://svs.gsfc.nasa.gov/13147|dead-url=no}}</ref><ref>{{cite web|url=https://www.noao.edu/news/2019/pr1904.php|title=Citizen Scientists Invited to Join Quest for New Worlds|website=[[美国国家光学天文台|NOAO]]|accessdate=22 February 2019|archive-date=2019-08-16|archive-url=https://web.archive.org/web/20190816040448/https://www.noao.edu/news/2019/pr1904.php|dead-url=no}}</ref>。

這顆白矮星的年齡雖然有30億年，周圍卻有[[星周盤]]存在。光譜資料中[[紅外過量]]與星周盤內兩個不同的還溫度符合：外部較低溫還溫度約480 K，內部較高溫環溫度550–1400 K。這可能是小行星因為恆星重力碎裂形成的[[岩屑盤]]。

天文學家已經使用[[凱克天文台]]對LSPM J0207+3331進行觀測以研究，並已經有論文被[[天文物理期刊|天文物理期刊通訊]]接受<ref>{{cite arXiv|eprint=1902.07073|last1=Debes|first1=John H.|title=A 3 Gyr White Dwarf with Warm Dust Discovered via the Backyard Worlds: Planet 9 Citizen Science Project|last2=Thevenot|first2=Melina|last3=Kuchner|first3=Marc|last4=Burgasser|first4=Adam|last5=Schneider|first5=Adam|last6=Meisner|first6=Aaron|last7=Gagne|first7=Jonathan|last8=Faherty|first8=Jaqueline K.|last9=Rees|first9=Jon M.|last10=Allen|first10=Michaela|last11=Caselden|first11=Dan|last12=Cushing|first12=Michael|last13=Wisniewski|first13=John|last14=Allers|first14=Katelyn|author15=The Backyard Worlds: Planet 9 Collaboration|author16=The Disk Detective Collaboration|class=astro-ph.SR|year=2019}}</ref>。
