This is the definitive treatment of the phenomenology of galaxies--a clear and comprehensive volume that takes full account of the extraordinary recent advances in the field. The book supersedes the classic text Galactic Astronomy that James Binney wrote with Dimitri Mihalas, and complements Galactic Dynamics. Assuming that its radius does not change over these intervals, the long-term variation in activity level appears to produce a temperature variation of 15 K, which corresponds to a variation in visual magnitude (V) of 0.014.

The book supersedes the classic text Galactic Astronomy that James Binney wrote with Dimitri Mihalas, and complements Galactic Dynamics by Binney and Scott Tremaine. ![]() It will be invaluable to researchers and is accessible to any student who has a background in undergraduate physics. The book draws on observations both of our own galaxy, the Milky Way, and of external galaxies. The two sources are complementary, since the former tends to be highly detailed but difficult to interpret, while the latter is typically poorer in quality but conceptually simpler to understand. Binney and Merrifield introduce all astronomical concepts necessary to understand the properties of galaxies, including coordinate systems, magnitudes and colors, the phenomenology of stars, the theory of stellar and chemical evolution, and the measurement of astronomical distances. The book's core covers the phenomenology of external galaxies, star clusters in the Milky Way, the interstellar media of external galaxies, gas in the Milky Way, the structure and kinematics of the stellar components of the Milky Way, and the kinematics of external galaxies. Throughout, the book emphasizes the observational basis for current understanding of galactic astronomy, with references to the original literature. Offering both new information and a comprehensive view of its subject, it will be an indispensable source for professionals, as well as for graduate students and advanced undergraduates. First published in 1998. James Binney is Professor of Physics and a Fellow of Merton College, University of Oxford. His books include Galactic Dynamics (Princeton), which he coauthored with Scott Tremaine. Michael Merrifield is University Lecturer in Astronomy at the University of Southampton. Ran,, -09°697, 742.00, 144, 22049, 16537, 1084, 1557, 130564,. Database references Epsilon Eridani ( ε Eridani, abbreviated Epsilon Eri, ε Eri), also named Ran, is a in the southern of, at a of 9.46° south of the. This allows it to be visible from most of Earth's surface. At a distance of 10.5 (3.2 ) from the, it has an of 3.73. It is the individual star or visible to the unaided eye. The star is estimated to be less than a billion years old. Because of its relative youth, Epsilon Eridani has a higher level of than the present-day Sun, with a 30 times as strong. Its period is 11.2 days at the equator. Epsilon Eridani is smaller and less massive than the Sun, and has a comparatively lower level of. It is a of K2, which means that energy generated at the core through of is emitted from the surface at a temperature of about 5,000 (8,500 ), giving it an orange hue. The ε Eridani (Latinised as Epsilon Eridani) was established in 1603. It may be a member of the of stars that share a similar motion through the, implying these stars shared a common origin in an. Its nearest neighbour, the system, will have a close encounter with Epsilon Eridani in approximately 31,500 years when they will be separated by about 0.93 ly (0.29 pc). The motion of Epsilon Eridani along the line of sight to Earth, known as the, has been regularly observed for more than twenty years. Periodic changes in its value of a orbiting the star, making it one of the closest star systems with a candidate. The discovery of the planet has been controversial because of the amount of background noise in the radial velocity data, particularly in the early observation, but many astronomers now regard the planet as confirmed. In 2016 it was given the alternative name AEgir [ ]. The Epsilon Eridani system also includes two belts of rocky: at about 3 AU and 20 AU from the star. The orbital structure could be maintained by a hypothetical second planet, which if confirmed would be Epsilon Eridani c. Epsilon Eridani hosts an extensive outer of remnant left over from the system's formation. As one of the nearest with a planet, Epsilon Eridani has been the target of several observations in the.
