Molecular Line Profiles from Contracting Dense Cores (2010)
Stahler, Steven W., Yen, Jeffrey J.
We recently proposed that molecular cloud dense cores undergo a prolonged period of quasi-static contraction prior to true collapse. This theory could explain the observation that many starless cores...
The Dynamical Evolution of the Pleiades (2010)
Converse, Joseph M., Stahler, Steven W.
We present the results of a numerical simulation of the history and future development of the Pleiades. This study builds on our previous one that established statistically the present-day structure...
The Orbital Decay of Embedded Binary Stars (2009)
Young binaries within dense molecular clouds are subject to dynamical friction from ambient gas. Consequently, their orbits decay, with both the separation and period decreasing in time. A simple...
The Distribution of Stellar Mass in the Pleiades (2008)
Converse, Joseph M., Stahler, Steven W.
As part of an effort to understand the origin of open clusters, we present a statistical analysis of the currently observed Pleiades. Starting with a photometric catalog of the cluster, we employ a...
Haisch Jr., Karl E., Greene, Thomas P., Barsony, Mary, Stahler, Steven W.
We present new near-IR observations of 76 Class I/flat-spectrum objects in the nearby (d < 320 pc) Perseus, Taurus, Chamaeleon I and II, rho Ophiuchi, and Serpens dark clouds. These observations are...
Trapped Protostellar Winds and their Breakout (2003)
Wilkin, Francis P., Stahler, Steven W.
Observations show that high-velocity jets stem from deeply embedded young stars, which may still be experiencing infall from their parent cloud cores. Yet theory predicts that, early in this buildup,...
Star Formation in Space and Time: Taurus-Auriga (2002)
Palla, Francesco, Stahler, Steven W.
To understand the formation of stellar groups, one must first document carefully the birth pattern within real clusters and associations. In this study of Taurus-Auriga, we combine pre-main-sequence...
The Structure and Evolution of Magnetized Cloud Cores in a Zero--Density Background (2001)
Curry, Charles L., Stahler, Steven W.
Molecular-line observations of star-forming cloud cores indicate that they are not the flattened structures traditionally considered by theory. Rather, they are elongated, perhaps in the direction of...
Binary Masses as a Test for Pre-Main-Sequence Models (2001)
Palla, Francesco, Stahler, Steven W.
Observations of binaries have traditionally provided the means for ascertaining stellar masses. Here, we use the published data on 8 pre-main-sequence pairs to gauge the accuracy of our own, recently...
