Absence of a Correlation between White Dwarf Planetary Accretion and Primordial Stellar Metallicity

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Sydney Jenkins, Andrew Vanderburg, Allyson Bieryla, David W. Latham, Mariona Badenas-Agusti | Summary: Over a quarter of white dwarfs have photospheric metal pollution, which is evidence for recent accretion of exoplanetary material. While a wide range of mechanisms have been proposed to account for this pollution, there […]

A Potential Second Shutoff from AT2018fyk: An updated Orbital Ephemeris of the Surviving Star under the Repeating Partial Tidal Disruption Event Paradigm

Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Eric Coughlin, Muryel Guolo, Thomas Wevers, Chris Nixon | Summary: The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypothesized that this behavior results from a repeating partial […]

Late-time radio brightening and emergence of a radio jet in the changing-look AGN 1ES 1927+654

Kavli Affiliate: Erin Kara | First 5 Authors: Eileen T. Meyer, Sibasish Laha, Onic I. Shuvo, Agniva Roychowdhury, David A. Green | Summary: We present multi-frequency (5-345 GHz) and multi-resolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic nuclei (CL-AGN). The source was first designated a […]

A high-resolution imaging survey of massive young stellar objects in the Magellanic Clouds

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Venu M. Kalari, Ricardo Salinas, Hans Zinnecker, Monica Rubio, Gregory Herczeg | Summary: Constraints on the binary fraction of young massive stellar objects (mYSOs) are important for binary and massive star formation theory. Here, we present speckle imaging of 34 mYSOs located in the Large (1/2 $Z_{odot}$) […]

Correlated mid-infrared and X-ray outbursts in black hole X-ray binaries: A new route to discovery in infrared surveys

Kavli Affiliate: Erin Kara | First 5 Authors: Chris John, Kishalay De, Matteo Lucchini, Ehud Behar, Erin Kara | Summary: The mid-infrared (MIR; $lambdasimeq3 – 10mu$m) bands offer a unique window into understanding accretion and its interplay with jet formation in Galactic black hole X-ray binaries (BHXRBs). Although extremely difficult to observe from the ground, […]

The hyperplane of early-type galaxies: using stellar population properties to increase the precision and accuracy of the fundamental plane as a distance indicator

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Matthew Colless, Arjen van der Wel, Sam P. Vaughan, Khaled Said | Summary: We use deep spectroscopy from the SAMI Galaxy Survey to explore the precision of the fundamental plane of early-type galaxies (FP) as a distance indicator for future single-fibre spectroscopy surveys. We study […]
