Ilmu Astronomi Populasi bintang di Galaksi advertisement. Beberapa parameter lain yang menunjukkan properti yang sama adalah: Semakin kecil basis set n, mnsemakin mudah adalah populasi komposit dan, akhirnya, sejarah Galactic untuk diungkap Mengidentifikasi SSPS individu mungkin sulit di galaksi yang kompleks, tapi, mungkin untuk SSP yang dirangkai dalam pola agak sederhana.

Komponen Utama misalkan pembentukan bintang pada piringan dengan memperkaya serangkaian pembentukan SSP disertai meningkatnya kecepatan rotasi terhadap pusat. Kita berharap untuk menyederhanakan apa yang mungkin menjadi masalah yang rumit untuk menemukan salah satu pola dalam Populasi Komponen Utama.

Korelasi antara bebrbagai parameter seperti: Laju pembentukan bintang SFR: Baade’s famous plate, reproduced from Majewski ed.

High contrast zoom of previous image to show the fptometri resolution of the “Baade sheet”. Baade’s definition of populations based on CMD type. A modern HR diagram of the solar neighborhood. No red and blue supergiants now known to be an age effect.

Populasi bintang di Galaksi

Has short period, cluster Cepheids i. Bintang dengan berbagai umur dan banyak awan gas Spheroidal Component: Summary tables from the Vatican Conference proceedings. This book makes great reading, because all of the conversations of participants have been preserved and recorded in the proceedings.


Note that the ages listed in the table are based on well outdated stellar evolution models, and are too small by about bintag factor of two.

Though it should be kept in mind that this conventional picture is still debated. Note the difference between the luminous stellar halo, and the dark matter halo postulated to exist and in which the luminous matter is embedded.

Another view of the Milky Way and its populations. From BuserScience, Schematic view of the major components that make up the Galaxy’s overall structure, shown in a cross section perpendicular to the plane of rotation and going through the sun and the Galactic center.

From the observer’s vantage point at the sun’s position, the directions to the North NGP and South SGP Galactic Poles are particularly suitable for studying the layered structure and other properties of the stellar disks and halo, whereas the concentration of gas and dust in the extreme disk severely obstructs observations of the distant bulge at visual-optical wavelengths.

Fotomteri central parts of the Galaxy are better accessible through longer wavelength infrared and radio observations. Cartoon left and modeled right illustration of the Galactic dark matter halo.


In right figure the plot is only of bintanng density of dark matter in a simulated Milky Way halo, with light on a logarithmic scale andlight years vintang a side. Galactic Structure Flat disk: Ellipsoid of velocity dispersions for a Schwarzchild stellar population with multivariate gaussian velocities, defined by: N-body simulations by Quinn et al. No vertical chemical and kinematic gradients expected in the Thick Disk Intermediate phase Halo-Disk Continuity of the velocity ellipsoids and asymmetric drift Thick disk: For examples, stellar samples selected on the basis of the chemical or kinematic properties e.

High luminosity objects which can be observed up to great distances, easy to identify and to measure their distance e.

bihtang It is assumed that tracers are representative of the whole population. These measure directly the bulk of the objects which constitute the target populations e. Galaxy models An alternative approach: Similarly, the estimation of the halo flatness is correlated to the power-index, and it is also sensitive to the separation between halo and thick disk stars.
