However, these ranges span only a fraction of the planetary parameter estimates, which vary over 10−5≲Λ i ≲1010, 102≲R m≲105, and (10^{-6} lesssim Lambda _{d}^ lesssim 10^{7}) as detailed in the "Discussion" section.
As with planetary nebulae, estimates of the abundance of elements in H II regions are subject to some uncertainty.
In a substantial fraction of the team's simulations, the moon's orbital tilt ended up being 10° or more, the amount that planetary scientists estimate the nascent moon would have had based on today's orbital tilt.
Outside consultants estimating planetary science mission costs for the next decade have produced huge numbers for the largest proposed missions, forcing some painful and unprecedented recommendations in the committee's report.
In "Example MiXO configurations and performance" section, we show example MiXO configurations suitable for planetary missions and estimate the performances in comparison to an alternative approach, micro-pore optics (MPO).
Geophysicist Steven Ward and planetary physicist Erik Asphaug estimate, in the May issue of Icarus (see ScienceNOW, 23 November 1999), that there's a 1-in-47 chance over the next 1000 years that a foreign body at least 60 meters across will splash into the Atlantic and send a tsunami greater than 5 meters high rolling over New York City.
An advantage of this formulation is that it depends on quantities that can be estimated for planetary cores (Table 3).
The factors were the following: (1) planetary geomagnetic activity level estimated by Ap-index and divided into five levels; (2) gender – males and females; (3) blood pressure degree – persons in the group examined were divided into hypotensive, normotensive and hypertensive.
Located on the border with Circinus is the unusual planetary nebula NGC 5189, estimated to be around 1750 light-years away from Earth.
Because temperatures of proto-planetary disks are estimated to range between T = 400 K and 50 K at a radius between 2 AU and 50 AU (Willacy and Langer, 2000), we discuss the effect of reducing the temperature on the magnetic alignment process.
