Morphology of Hydrodynamic Winds: A Study of Planetary Winds in Stellar Environments [PDF]
, 2018 Bathed in intense ionizing radiation, close-in gaseous planets undergo hydrodynamic atmospheric escape, which ejects the upper extent of their atmospheres into the interplanetary medium.

An Embedded Disk (eDisk) in the IceAge: Investigating the Jet and Outflow from Ced 110 IRS4
The Astronomical JournalWe present a comprehensive study of the large-scale structure, jet and outflow morphology, and kinematics of the Class 0/I protostellar binary Ced 110 IRS4, using JWST NIRCam (F150W and F410M) and MIRI MRS observations from the JWST ERC program IceAge ...

Magnetic Braking Formulation for Sun-Like Stars: Dependence on Dipole Field Strength and Rotation Rate [PDF]
, 2012 We use two-dimensional axisymmetric magnetohydrodynamic simulations to compute steady-state solutions for solar-like stellar winds from rotating stars with dipolar magnetic fields.

Accretion from Stellar Winds [PDF]
International Astronomical Union Colloquium, 1988 AbstractRecent calculations have demonstrated that accretion from a stellar wind is very probably unsteady. The average rate of accretion of angular momentum is lower by about a factor 5 than the rate at which angular momentum is deposited into the Bondi-Hoyle accretion cylinder.

EPISODE. III. The Nested Jet/Outflow Morphology of EC 53 Revealed by JWST and ALMA
The Astrophysical JournalWe present an extensive study of the structure and kinematics of the jet and outflow of EC 53, a Class I protostar with a quasiperiodic variability, using combined James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA ...

Testing the Rossby Paradigm: Weakened Magnetic Braking in Early K-type Stars
The Astrophysical JournalThere is an intricate relationship between the organization of large-scale magnetic fields by a stellar dynamo and the rate of angular momentum loss due to magnetized stellar winds. An essential ingredient for the operation of a large-scale dynamo is the

New insight into the physics of atmospheres of early type stars [PDF]
The phenomenon of mass loss and stellar winds from hot stars are discussed. The mass loss rate of early type stars increases by about a factor of 100 to 1000 during their evolution.

Molecules in Stellar Winds [PDF]
Symposium - International Astronomical Union, 1992 High mass-loss molecular winds are characterstic of two important phases of stellar evolution, very young protostars and stars on the asymptotic branch. Novel chemical processes in these winds suggest a variety of new astronomical observations.

Weakened Magnetic Braking in the Exoplanet Host Star 51 Peg
The Astrophysical Journal LettersThe consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star could be experiencing a magnetic grand minimum.
