This large range also arises from the planet's high degree of orbital eccentricity.
Two different samples of systems were observed: one containing low - eccentricity outer planets, and the other containing high - eccentricity outer planets.
Our results also imply that the majority of high - eccentricity planets are not embedded in multiple stellar systems (24 out of 34), since our detection limits exclude the presence of a stellar companion.
This star is located about 224 AUs away on average (a semi-major axis of 14.39» at a HIPPARCOS distance of 50.87 light - years) with an orbital period around 2,000 years and an extremely high orbital eccentricity of 0.91.
Furthermore fitting this period results in an implausibly high eccentricity that crosses the orbits of the other planets.
«By comparing the actual New Horizons observations of Charon to the various predictions, we can see what fits best and discover if Charon could have had a subsurface ocean in its past, driven by high eccentricity.»
In the case of Edasich, however, the high orbital eccentricity of its companion made its motion distinguishable from stellar pulsation as the cause of the observed velocity variations.
The high circular orbit has an eccentricity of 0.08 (+0.19 / -.08) and a period 17.5 days (UH news release; and Tuomi et al, 2014).
In the 1970s and 1980s, some astronomers suggested that observed flare activity or light minima in EV Lac's light curve between flares could have been caused by an eclipsing companion with an orbital period of around 45 years and a high orbital eccentricity (e ~ 0.5)(G. Sh.
A treasure trove of playful eccentricity, with a small dose of high drama.
«Weird» is the term appropriate to this hub of eccentricities, which lays claim to endearing titles including host to the world's largest bookstore and site of an inexplicably high number of bridges.
Raymo and Paillard have a good story about the 100KYr cycle arising from the modulation of the precessional cycle by the changes in the Earth's orbital eccentricity, coupled with some glacial dynamical effects which «rectify» the high frequency precessional signal.
MILANKOVITCH CYCLES overall favor N.H. cooling and an increase in snow cover over N.H high latitudes during the N.H summers due to the fact that perihelion occurs during the N.H. winter (highly favorable for increase summer snow cover), obliquity is 23.44 degrees which is at least neutral for an increase summer N.H. snow cover, while eccentricity of the earth's orbit is currently at 0.0167 which is still circular enough to favor reduced summertime solar insolation in the N.H. and thus promote more snow cover.
«An examination of the fossil record indicates that the key junctures in hominin evolution reported nowadays at 2.6, 1.8 and 1 Ma coincide with 400 kyr eccentricity maxima, which suggests that periods with enhanced speciation and extinction events coincided with periods of maximum climate variability on high moisture levels.»
A link between Earth's orbital eccentricity and NADW production with high eccentricity leading to low production of NADW and vice versa is proposed by Crowley and Kim (1992).
An ~ 100kyr periodicity in fast - spreading seafloor bathymetry, and relatively low present - day eruption rates, at a time of high sea - level and decreasing orbital eccentricity suggest a longer term sensitivity to sea - level and orbital variations associated with Milankovitch cycles.
Regardless of the carbon source (s), it has been shown that the hyperthermals were astronomically paced, spurred by coincident maxima in the Earth's orbit eccentricity and spin axis tilt [17], which increased high - latitude insolation and warming.
Palaeoclimate studies show that differences in the manner in which the Earth orbited the Sun during the Last Interglacial are sufficient to explain the higher temperatures over most parts of the Northern Hemisphere, particularly due to greater axial tilt and eccentricity compared with the present day orbital configuration.
Simulation of non-linear accumulation and bioturbation effects on precession - forced basinal carbonate cycles demonstrate that variance can be transferred from the precession into the eccentricity band18, generating «redder», i.e., higher ρ1 values.
