We have used the latter to make the first determination of Saturn's Love number from observations, <i>k</i><sub>2</sub>=0.390 ± 0.024, a value larger than the commonly used theoretical value of 0.341 (Gavrilov & Zharkov, 1977), but compatible with more recent models (Helled & Guillot, 2013) for which the static <i>k</i><sub>2</sub> ranges from 0.355 to 0.382. Depending on the assumed spin for Saturn's interior, the new constraint can lead to a significant reduction in the number of potential models, offering great opportunities to probe the planet's interior. In addition, significant tidal dissipation within Saturn is confirmed (Lainey et al., 2012) corresponding to a high present-day tidal ratio <i>k</i><sub>2</sub>/<i>Q</i>=(1.59 ± 0.74) × 10<sup>−4</sup> and implying fast orbital expansions of the Moons. This high dissipation, with no obvious variations for tidal frequencies corresponding to those of Enceladus and Dione, may be explained by viscous friction in a solid core, implying a core viscosity typically ranging between 10<sup>14</sup> and 10<sup>16</sup> Pa.s (Remus et al., 2012). However, a dissipation increase by one order of magnitude at Rhea's frequency could suggest the existence of an additional, frequency-dependent, dissipation process, possibly from turbulent friction acting on tidal waves in the fluid envelope of Saturn (Ogilvie & Lin, 2004; Fuller et al. 2016).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"New constraints on Saturn's interior from Cassini astrometric data","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Astrometry; Interior; Saturn","OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2019-07-09","DateCreate":"2017-05-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000385478100022","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.icarus.2016.07.014"},"refs":null,"anarec":{"AnaID":285343,"PubliDate":2017,"Pagination":"286-296","XtraPublOfAnaID":null,"ISBN":null,"Volume":"281","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":261659,"SerRR":"Icarus.
