2MASS J01375356-6030414 ^[
10
] eller HD 10180 ar en ensam stjarna belagen i den norra delen av stjarnbilden Lilla vattenormen . Den har en skenbar magnitud av ca 7,33 ^[
2
] och kraver atminstone en stark handkikare for att kunna observeras. ^[
11
] Baserat pa parallaxmatning inom Hipparcosuppdraget pa ca 25,6 ^[
1
] mas, beraknas den befinna sig pa ett avstand pa ca 127 ljusar (ca 39 parsek ) fran solen . ^[
12
] Den ror sig bort fran solen med en heliocentrisk radialhastighet pa ca 35 km/s. ^[
3
]

Stjarnan ar kand for sitt stora planetariska system och sedan dess upptackt har minst sju exoplaneter , och mojligen sa manga som nio, observerats som kretsar kring den, vilket gor den till det potentiellt storsta av alla kanda planetsystem inklusive solsystemet . ^[
13
]^[
6
] (Andra stjarnor med ett stort kant antal planeter ar Kepler-90 , Trappist-1 , Kepler-11 och 55 Cancri .)

Egenskaper [ redigera | redigera wikitext ]

HD 10180 ar en solliknande gul ^[
14
] till vit stjarna i huvudserien av spektralklass G1 V. ^[
3
] Den har en massa som ar ca 1,1 ^[
5
] solmassor , en radie som ar ca 1,2 ^[
5
] solradier och har ca 1,5 ganger solens utstralning av energi ^[
6
] fran dess fotosfar vid en effektiv temperatur av ca 5 900 K. ^[
7
] En undersokning 2015 har visat att det inte finns nagra foljeslagare pa projicerade avstand over 13 astronomiska enheter . ^[
15
]

Planetsystem [ redigera | redigera wikitext ]

Ar 2010 meddelade en forskargrupp under ledning av Christophe Lovis vid Geneves universitet att stjarnan har minst fem exoplaneter, och mojligen sa manga som sju. ^[
6
]^[
16
] Planeterna upptacktes med hjalp av HARPS- spektrografen , i samverkan med ESO:s 3,6 m-teleskop vid La Silla-observatoriet i Chile , med anvandning av dopplerspektroskopi .

I april 2012 overlamnade astronomen Mikko Tuomi fran University of Hertfordshire en rapport till Astronomy and Astrophysics med foreslag till en nioplanetsmodell for systemet. Genom bearbetning av data med Bayesian sannolikhetsanalys kunde tidigare kanda planeters parametrar reviderades och ytterligare bevis hittas for den innersta planeten (b) samt bevis for ytterligare tva planeter (i och j) .
