Kosmicheskie luchi na Voyadzhere-1

Zapushennyi v 1977 godu v bol'shoe puteshestvie k vneshnim planetam, odin iz bliznecov Voyadzherov po
schastlivoi sluchainosti poletel v tom napravlenii, v kotorom nashe Solnce dvizhetsya
otnositel'no blizkih zvezd.
35 let spustya Voyadzher-1, pohozhe, priblizilsya k granice mezhdu solnechnoi geliosferoi i
mezhzvezdnym prostranstvom.

Granica solnechnoi sistemy (s.s.) lezhit znachitel'no dal'she. Soglasno moim
raschetam s.s. tipa nashei rodilas' iz pervichnogo puzyrya, srednii radius kotorogo
58000 a.e.., dlya mass 1-60. Eto priblizitel'no chetvert' rasstoyaniya do zvezdy
Proksima Centavra. Larson modeliroval s.s., tochnee solnce, ishodya iz rascheta
23000 a.e.. Hotya u nas sovershenno raznye podhody, odnako, sovpadenie v
predelah poryadka dayut nadezhdu, chto granica s.s. zakanchivaetsya imenno v etih
predelah, poetomu Voyadzheram letet' i letet'.

Da, Voyadzhery, stavyat pered nami vopros za voprosom, otvety na kotorye my poka ne
znaem. Odno tormozhenie apparatov chego stoit, skol'ko gipotez bylo vydvinuto!
Soobsheniya o tom, chto Voyadzhery vot-vot pokinut poslednie rubezhi s.s. regulyarno
poyavlyayutsya nachinaya s 2005 goda. V nachale, prishlo soobshenie, chto skorost'
chastic letyashih ot solnca upal do nulya. Lyubopytno, a chto s nimi proishodit
dal'she: akkumuliruyutsya v etoi zone ili letyat obratno? Dalee, ozhidanie granic
geliopauzy i nachalo davleniya potoka chastic izvne. I vot on grafik, pered Vami,
pora radovat'sya. Odnako, soglasno priznaniyu Roberta Dekera "V itoge, mozhno
skazat', chto my ne znaem, gde v real'nosti konchaetsya Solnechnaya sistema". Po
semu, Vash veselyi yumor ya prinimayu. Hotya utochnim, verhnii predel granicy vse zhe
my znaem. Eto sfera Hilla.

A kakoe vliyanie vnosyat planety v razmer sfery Hilla? Izmenilsya by ee radius,esli by ih ne bylo?

Radius Hilla dlya s.s. opredelyaetsya otnositel'no blizhaishei k nam zvezdy
Proksimy Centavra. Massa planet i vsego ostal'nogo v obshei masse s.s. ne
prevyshaet 0.14 % massy Solnca.

Zadacha bol'she chem 3 tel ne reshena. A voobshe, esli rassmatrivat' prityazhenie zemli i vrashenie ee po orbite kak skazhem rabotu sily solnechnogo prityazheniya , ne umen'shaetsya
li pri etom gravitacionnyi potencial zvezdy? Vopros glupyi,navernoe,no interesnyi.)

V OTO energiya gravitacionnogo polya ne lokalizuetsya i zakon sohraneniya energii ne rabotaet .

Princip superpozicii v gravitacionnom pole ne rabotaet iz-za nelineinosti . Solnce prityagivaet ne tol'ko Zemlyu i Lunu,no i samo vzaimodeistvie mezhdu nimi. S'ezhivaetsya
vidimo.
