Following the tidal trail: a history of modeling the Magellanic Stream

Astrophysics and Space Science
The formation of the Magellanic Stream has puzzled astronomers for decades. In this review, we outline the history of our understanding of the Magellanic System highlighting key observations that have revolutionized thinking of its evolution.

The Dynamics of the Magellanic Stream

Publications of the Astronomical Society of Australia, 1976
In this talk I shall describe briefly some of the theoretical ideas of the origin of the Magellanic Stream and then give a more personal view of the results of model fitting.The Magellanic Stream definitely seems to be an extragalactic feature: the apparent connection of the Stream to the Magellanic Clouds and the continuity of the radial velocity ...

Ionized Gas in the Magellanic Stream [PDF]

EAS Publications Series, 2012
We report on new optical emission line observations toward the northern part of the Magellanic Stream. Using the Wisconsin H-Alpha Mapper (WHAM), we have detected Hα emission toward 17 directions spread across 50 ∘ of the Stream. We find strong variation in the Hα surface brightness with no significant correlation with Magellanic longitude. We compare

The Origin of the Magellanic Stream

1989
New observations of the Magellanic Stream are used in a recent discrete ram-pressure theory which proposes that the signs of interaction in the Magellanic System point to a collision event some 2–4 × 108 years ago, and that the collisions between the inter-Cloud gas and a discrete halo produce the Magellanic Stream.

The Magellanic Stream: New Observations

Publications of the Astronomical Society of Australia, 1989
AbstractNew HI observations of the Magellanic Stream have been made using the Parkes 64 m telescope. These observations highlight in detail its complicated structure and uncover new features of the Stream. The extreme velocity clouds (EVCs) are morphologically linked to the Stream indicating that these HI clouds are very likely truly part of the Stream.

A possible deformation of the Magellanic Stream

Astronomical & Astrophysical Transactions, 1996
Abstract The existance of a low LSR-velocity neutral hydrogen in the Magellanic Stream is possibly confirmed with RATAN-600 observations. The displacement of these broad signals with the growing negative velocity occurs in the same manner as the N-warp in our Galaxy, but the scale of the event is approximately 3 times large.

A New Model of the Magellanic Stream

1990
Lynden-Bell (1988) has estimated the mass of the Galaxy within a Galactocentric radius of 50 kpc to be ~ 1.8 × 1012 M⊙ from the kinematics and dynamics of the Magellanic Stream. In contrast Zaritsky et al. (1989), using the statistical procedure developed by Little and Tremaine (1987), have found this mass to be 3.6 × 1011 M⊙ from the orbits of ...
