The subje
t of this dissertation is intera
tion between the mean motion resonan-
es and the Yarkovsky e e
t. This intera
tion o
urs when an asteroid due to the
hanges of its orbital semi-major axis (
aused by the Yarkovsky e e
t) rea
h the re-
sonan
e. The resonan
e indu
es a periodi
os
illations in the asteroid's semi-major
axis around its
enter. The Yarkovsky e e
t exa
tly
auses the permanent (se
ular)
evolution of the orbital semi-major axis. As a result of their intera
tion the mean
semi-major axis drift speed is modi ed with respe
t to the one
aused solely by
Yarkovsky. One of the main goals of this investigation was to study this intera
tion,
and to establish and de ne how the time that an asteroid spend in the resonan
e
depends on some
hara
teristi
s of this resonan
e, as well as of the asteroid itself.
So far, the impa
t of the resonan
e on the semi-major axis drift speed has not been
studied to that extent neither from that point of view. In order to study the afo-
rementioned intera
tion the orbital motion of test parti
les a
ross the resonan
es is
numeri
ally simulated using ORBIT9 integrator. The most important result of this
dissertation
ertainly is determination of fun
tional relation between on one side the
time-period that obje
ts spend inside a resonan
e, and, on the other side, the semi-
majors axis drift speed, the orbital e
entri
ity and the resonan
e strength. In this
work not only that existen
e of the above-mentioned relationship is
on rmed, but
for the rst time it was expli
itly de ned. Two the most interesting results are that
the time spent in the resonan
e is inversely proportional to the semi-major axis drift
speed
aused by the Yarkovsky e e
t, and that this time is dire
tly proportional to
the resonan
e strength. |
