    Age is an important characteristic of a planetary system but also one that is difficult to determine. Assuming that the host star and the planets are formed at the same time, the challenge is to determine the stellar age. Asteroseismology provides precise age determination, but in many cases the required detailed pulsation observations are not available. Here we concentrate on other techniques Cited by: 2. Reach Us.

    Another matter is that of “calibration,” whereby dendrochronology (tree ring dating) is applied to the carbon 14 data to give a “corrected” date. This process adds another set of variables, especially if the tree ring data are tied to climate factors and atmospherics that differed from the environment of the Egyptian material being tested. Teach Astronomy - Oil painting of mathematician and philosopher Carl Friedrich Gauss by G. BiermannNo matter how hard we try, it isn't possible to make a measurement with absolute accuracy. Our tools lack perfect calibration and perfect resolution, and the nature of the universe adds.

    StellarNet provides a full range of calibration light sources and calibration services for its line of miniature spectrometer hardware that are traceable to the National Institute of Standards Technology (NIST-traceable). With over 20 years of experience, StellarNet designs instrumentation that meets the rigid quality standards for the most challenging testing requirements. Stellar Ages from Stellar Rotation Søren Meibom Harvard-Smithsonian Center for Astrophysics 60 Garden Street, Cambridge, MA, , USA email: [email protected] Abstract. Our ability to determine stellar ages from measurements of stellar rotation, hinges on how well we can measure the dependence of rotation on age for stars of different.

Learning Goals: The goal of this lab is to learn how to examine the spectrum of a star, and how measuring the intensity of those frequencies can reveal things about the star. Students will learn the relationship between color and temperature and will see how the chemical composition of a source can be determined from its emission or absorption line spectrum.

Various methods and tools are involved in stellar age estimation, an attempt to identify within reasonable degrees of confidence what the age of a star methods include stellar evolutionary models, membership in a given star cluster or system, fitting the star with the standard spectral and luminosity classification system, and the presence of a protoplanetary disk, among others.

An Introduction to Stellar Astrophysics aspires to provide the reader with an intermediate knowledge on stars whilst focusing mostly on the explanation of the functioning of stars by using basic physical concepts and observational results.

The book is divided into seven chapters, featuring both core and optional content: Cited by: Using the precise data from the Kepler exoplanet mission, astronomers from the Harvard-Smithsonian Center for Astrophysics have determined the rotation period measurements for 30 cool stars in the billion-year-old stellar cluster NGC The mass of a star is perhaps its most significant feature.
