Monitoring H Emission from the Wide-orbit Brown-dwarf Companion FU Tau B
Ya-Lin Wu, Yu-Chi Cheng, Li-Ching Huang +5
Monitoring mass accretion onto substellar objects provides insights into the geometry of the accretion flows. We use the Lulin One-meter Telescope to monitor H emission from FU…
Dynamical Masses of Young Stars Inferred from Two Transitions of CO with ALMA
Pranav H. Premnath, Ya-Lin Wu, Brendan P. Bowler +1
Stellar masses are fundamental but often difficult to measure. Thanks to the Atacama Large Millimeter Array (ALMA) and , dynamical masses of pre-main sequence stars can be pr…
High Precision Dynamical Masses of Pre-Main Sequence Stars with ALMA and Gaia
Patrick D. Sheehan, Ya-Lin Wu, Josh A. Eisner +1
The Keplerian rotation in protoplanetary disks can be used to robustly measure stellar masses at very high precision if the source distance is known. We present Atacama Large Milli…
The Intricate Structure of HH 508, the Brightest Microjet in the Orion Nebula
Ya-Lin Wu, Laird M. Close, Jinyoung Serena Kim +2
We present Magellan adaptive optics H imaging of HH 508, which has the highest surface brightness among protostellar jets in the Orion Nebula. We find that HH 508 actually has a…
Resolving the H-alpha-emitting Region in the Wind of Eta Carinae
Ya-Lin Wu, Nathan Smith, Laird M. Close +2
The massive evolved star Eta Carinae is the most luminous star in the Milky Way and has the highest steady wind mass-loss rate of any known star. Radiative transfer models of the s…
An ALMA and MagAO Study of the Substellar Companion GQ Lup B
Ya-Lin Wu, Patrick D. Sheehan, Jared R. Males +6
Multi-wavelength observations provide a complementary view of the formation of young directly-imaged planet-mass companions. We report the ALMA 1.3 mm and Magellan adaptive optics…
New Extinction and Mass Estimates from Optical Photometry of the Very Low Mass Brown Dwarf Companion CT Chamaeleontis B with the Magellan AO System
Ya-Lin Wu, Laird M. Close, Jared R. Males +9
We used the Magellan adaptive optics (MagAO) system and its VisAO CCD camera to image the young low mass brown dwarf companion CT Chamaeleontis B for the first time at visible wave…
On the Morphology and Chemical Composition of the HR 4796A Debris Disk
Timothy J. Rodigas, Christopher C. Stark, Alycia Weinberger +17
[abridged] We present resolved images of the HR 4796A debris disk using the Magellan adaptive optics system paired with Clio-2 and VisAO. We detect the disk at 0.77 \microns, 0.91…
Diffraction-limited Visible Light Images of Orion Trapezium Cluster With the Magellan Adaptive Secondary AO System (MagAO)
L. M. Close, J. R. Males, K. Morzinski +13
We utilized the new high-order (250-378 mode) Magellan Adaptive Optics system (MagAO) to obtain very high spatial resolution observations in "visible light" with MagAO's VisAO CCD…
High Resolution H alpha Images of the Binary Low-mass Proplyd LV 1 with the Magellan AO System
Y. -L. Wu, L. M. Close, J. R. Males +11
We utilize the new Magellan adaptive optics system (MagAO) to image the binary proplyd LV 1 in the Orion Trapezium at H alpha. This is among the first AO results in visible wavelen…
