In an H-R Diagram, stars with the smallest radius are found in the _______ of the diagram.?

HR may mean Human Resources in other contexts but in astronomy it means the Hertzsprung-Russell Diagram\n\nThe Hertzsprung-Russell diagram (usually referred to by the abbreviation H-R diagram or HRD, also known as a Colour-Magnitude diagram, or CMD) shows the relationship between absolute magnitude, luminosity, classification, and surface temperature of stars. \n\nThe diagram was created circa 1910 by Ejnar Hertzsprung and Henry Norris Russell, and represented a huge leap forward in understanding stellar evolution, or the 'lives of stars'. \n\nTo understand it you need to read up about the Morgan-Keenan spectral classification of stars.(see second link).\n\nThe short answer to what you ask is that the smallest Main Sequence stars are to be found at the bottom right ot the diagram and the smallest white dwarfs at the bottom left of the diagram.

Try red, white and blue stars!  That would be cute.

180°\n\nYesterday it was asked about a 5-pointed star.\n\nWell let us look at an n-pointed star\n\n1. Draw the circumscribing circle\n\n2. Join the vertices and create a regular n sides polygon inside the circumscribing circle\n\n3. Join each vertex to the centre\n\n4. Each point of the star is half the ange at the centree subtended on the same side.\n\n5. Each angle in the centre is equal as they are all subtended by equal chords as the sides of a regular polygon are equal.\n\n6. The sum of the angles at the centre of the circle = 360°\n\n7 So the sum of the angles at the circumference \n= sum of the angles of the star \n= ½ of 360°\n= 180°\n\nBONUS\n8 So each angle = 180°/n\n\nIf n = 5 each angle = 36°\nIf n = 7 each angle = (25 5/7)°

Hi. A new type of star was discovered and the astronomers cannot explain it yet. V838 Mon.  : http://hubblesite.org/newscenter/archive/releases/2003/10/text/ Pretty spectacular!

There is some special using of word "diameter".\n\nThe diameter of a subset of a metric space is the least upper bound of the distances between pairs of points in the subset.\n\nIn other words, diameter of a figure is a length of an interval, both vertex of which are within the figure.\n\nIf that is what you want and you want to find a diameter of a bar with sides 1 and 11, then the answer will be sqrt(122). This is because such interval will be a bar's diagonal.\n\nAnswer: sqrt(122).

Our sun is solidly in the average category. The exact average star is about 1,000,000 miles in diameter.\n\nMany other stars are spectacularly larger or smaller.\n\nThe lifespan of larger stars is shorter.  Srars become brighter at the end of their life, when hydrogen nuclei have been exhausted.  \n\nWhen stars become supernovae, other elements are created, the last one being iron, and much material is blown off.\n\nThen you have a dying monarch of light.  Red and white drwarfs.\n\nSites for stellar evolution info:\nhttp://search.yahoo.com/search?fr=ks&p=stellar+evolution\n\nOur sun has a remaining life span at current luminosity of 25 billion years.  That should give us enough time to figure out what to do when it goes into the ending processes.\n\nDetailed information about our sun and neighborhood:\nhttp://www.urantia.org/papers/toc.html\ngo to Paper 41 and Paper 57

First find the Big Dipper constellation (Ursa Major) Find the two stars farthest from the dipper handle. Draw an imaginary line from the bottom star through the top star and extend the line outward. The first bright star your imaginary line comes near is the North Star---that's north.\n\nThe website shown has a diagram of the above.

two circles, in parallel planes with the line connecting their centers forming right-angles with each plane in all directions. ... and the walls comprising the set of line segments one of whose end points is on one circel and the other end point on the other circle withe the property that the segments at each point on circle(A) is the minimum distance to circle(B).\n\n.. or, since you use the word "cylinder" in the question:\n\na cylinder, each of whose end-faces is a circle.

Thats one of the funniest questions I've ever heard, and definately a first.\n\nRatio...lol \n\nEven if someone could give you an accurate number it would be too large a number on the star side to even begin to comprehend, and too small a number on the freckle side to even be able to comprehend.  No one knows the exact number of stars, or even galaxies that contain them.

During a supernova, all matter is reduced to its smallest particles.  The smallest being the electrons and Hydrogen ion(H+). At a signifigant distance from "Ground 0," there occures a cooling phenominom that is a naturalphysical event.  Thus heat is an extensive physical property of most matted.  At this point electrons and H+ begin unifying into Hydrogen atoms.  At an even greater point two Hydrogen atoms fuse to product a Helium atom.  So on and so forth.  When these select few elements getr far enough from, "Ground 0" they are cooled to the point that fussion is no longer a natural phenominon.  At this distance in this time, of the story, things like planets, astroids and meteors form in extremely large massed of these elements to form minerals.  When these stellar bodies form H2O (water) they are capable of forming gassious H2O, CO2, H2, O2 and vary importantly C-4.  This place is called Earth any you are there.

all stars are formed from nebulae (the plural of nebula). Nebula is a term for a cloud of gas, and stars form from gas. Stars more massive than ~ 6 solar masses are expected to supernova, stars less massive than this (like our Sun, of course) become white dwarfs. After a supernova, there may be nothing left, or there could be a remnant: either a neutron star or a blackhole. If the remnant is more massive than around 3 solar masses it will probably end up as a blackhole. Stars are smallest when they are burning hydrogen into helium, which is what stars do during most of their lifetimes. Stars in this stage are sometimes called dwarfs. There are also two other kinds of "dwarfs": white dwarfs are burned-out stars mentioned above (the Learning Center has more info on these), and brown dwarfs are stars which never accumulated enough mass to start burning hydrogen.
