Tracing spiral density waves in M 81
We use SPITZER IRAC 3.6 and 4.5μm near infrared data from the Spitzer Infrared Nearby Galaxies Survey (SINGS), optical B, V and I and 2MASS Ks band data to produce mass surface density maps of M81. The IRAC 3.6 and 4.5μm data, whilst dominated by emission from old stellar populations, is corrected for small-scale contamination by young stars and PAH emission. The I band data are used to produce...
متن کاملSpiral density waves in a young protoplanetary disk.
Gravitational forces are expected to excite spiral density waves in protoplanetary disks, disks of gas and dust orbiting young stars. However, previous observations that showed spiral structure were not able to probe disk midplanes, where most of the mass is concentrated and where planet formation takes place. Using the Atacama Large Millimeter/submillimeter Array, we detected a pair of trailin...
متن کاملNonlinear Single-Armed Spiral Density Waves in Nearly Keplerian Disks
Single-armed, stationary density waves can exist even in disks with only weak selfgravity, provided that the rotation curve is dominated by a central mass. Such waves could play a significant role in the transport of angular momentum. By variational methods, we derive nonlinear versions of the dispersion relation, angular momentum flux, and propagation velocity in the tight-winding limit. The p...
متن کاملSpiral stellar density waves and the flattening of abundance gradients in the warm gas component of spiral galaxies
Motivated by recent observations of plateaus and minima in the radial abundance distributions of heavy elements in the Milky Way and some other spiral galaxies, we propose a dynamical mechanism for the formation of such features around corotation. Our numerical simulations show that the non-axisymmetric gravitational field of spiral density waves generates cyclone and anticylone gas flows in th...
متن کاملSTRONG DENSITY GRADIENTS ON DENSITY WAVES IN SPIRAL GALAXIES by KIN
The purpose of this study is to determine more accurately the marginal stability condition for axisymmetric waves since it is believed that an unstable axisymmetric wave could affect the amplification of spiral waves. An axisymmetric wave with a gradient term of velocity dispersion ( surface density ) is derived. Analysis of this axisymmetric wave with a gradient term for our own galaxy shows t...
