The Variation of Circumstellar Parameters through Early Stellar Evolution

Michael Connelley, Christian Flores, Bo Reipurth

We report on the evolution of extinction, mass accretion rate, and spectral index from analysis of SpeX observations and AllWISE spectral energy distributions, compared to stellar…

Using Gravity as an Age Indicator for Young Stars

Michael Connelley, Christian Flores, Bo Reipurth

The age of a young star is difficult to measure and yet is a fundamental property that is essential for understanding stellar evolution. Accurate age indicators across the early ph…

The Walkaway Star HP Tau/G2: Evidence for a Stellar Merger

Bo Reipurth, J. Bally, P. Friberg +6

HP~Tau/G2 is a luminous, short-period, fast-rotating G-type weak-line T Tauri star with a large radius, an oblate shape with gravity-darkening, little circumstellar material, and c…

iSHELL -band Survey of Class I and Flat Spectrum Sources: Magnetic field measurements in the protostellar phase

C. Flores, M. S. Connelley, B. Reipurth +2

We perform the first magnetic field strength survey of Class I and Flat Spectrum (FS) sources using -band observations with iSHELL. We obtained new observations of 42 Class I an…

Haro 5-2: A New Pre-Main Sequence Quadruple Stellar System

Bo Reipurth, C. Briceno, T. R. Geballe +9

We have discovered that the Halpha emission line star Haro 5-2, located in the 3-6 Myr old Ori OB1b association, is a young quadruple system. The system has a 2+2 configuration wit…

Is T Tauri North a 'Classical' T Tauri star?

Christian Flores, Bo Reipurth, Michael S. Connelley

We present high-resolution - and -band spectroscopic observations of the archetypal T Tauri star T Tau North. Synthetic spectral modeling is used to derive the -band tempe…

Measuring the magnetic field of young stars using iSHELL observations: BP Tau and V347 Aur

Christian Flores, Michael S. Connelley, Bo Reipurth +1

While it has been suggested that there is a connection between the magnetic properties and the internal structure of young stars, there have not been enough magnetic measurements t…
