Disc breaking through forced eccentricity growth
Madeline Overton, Rebecca G. Martin, Stephen H. Lubow +1
Motivated by misaligned discs observed in eccentric orbit Be/X-ray binaries, we examine the evolution of a retrograde disc around one component of an eccentric binary with hydrodyn…
Global 3-D Simulations of Magnetospheric Accretion: II. Hot Spots, Equilibrium Torque, Episodic Wind, and Midplane Outflow
Zhaohuan Zhu
Global 3-D magnetohydrodynamical simulations have been conducted to study magnetospheric accretion around stars with various spin rates. For slow rotators, characterized by a fastn…
Stable Case BB/BC Mass Transfer to Form GW190425-like Massive Binary Neutron Star Mergers
Ying Qin, Jin-Ping Zhu, Georges Meynet +14
On April 25th, 2019, the LIGO-Virgo Collaboration discovered a Gravitational-wave (GW) signal from a binary neutron star (BNS) merger, i.e., GW190425. Due to the inferred large tot…
Fragmentation of Dense Rotation-Dominated Structures Fed by Collapsing Gravomagneto-Sheetlets and Origin of Misaligned 100 au-Scale Binaries and Multiple Systems
Yisheng Tu, Zhi-Yun Li, Zhaohuan Zhu +1
The majority of stars are in binary/multiple systems. How such systems form in turbulent, magnetized cores of molecular clouds in the presence of non-ideal MHD effects remains rela…
Retrograde discs around one component of a binary are unstable to tilting
Madeline Overton, Rebecca G. Martin, Stephen H. Lubow +1
With hydrodynamic simulations we show that a coplanar disc around one component of a binary can be unstable to global tilting when the disc orbits in a retrograde direction relativ…
Resolving the Binary Components of the Outbursting Protostar HBC 494 with ALMA
Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez +15
Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevat…
Effective two-body scatterings around a massive object
Yihan Wang, Saavik Ford, Rosalba Perna +3
Two-body scatterings under the potential of a massive object are very common in astrophysics. If the massive body is far enough away that the two small bodies are in their own grav…
Fast nodal precession of the disc around Pleione requires a broken disc
Rebecca G. Martin, Stephen Lepp
Pleione is a Be star that is in a 218 day orbit with a low-mass binary companion. Recent numerical simulations have shown that a Be star disc can be subject to breaking when materi…
The eclipse of the V773 Tau B circumbinary disk
M. A. Kenworthy, D. González Picos, E. Elizondo +9
A deep (~70%) and extended (~150 days) eclipse was seen towards the young multiple stellar system V773 Tau in 2010. We interpret it as due to the passage of a circumbinary disk aro…
Magnetically-gated accretion model: application to short bursts in the intermediate polar V1223 Sgr
J. -M. Hameury, J. -P. Lasota, A. W. Shaw
Some intermediate polars show outbursts that are much shorter than those observed in normal dwarf novae, and whose origin has remained unelucidated for a long time. We examine here…
The disk of FU Orionis viewed with MATISSE/VLTI: first interferometric observations in and bands
F. Lykou, P. Ábrahám, L. Chen +30
The disk of FU Orionis is marginally resolved with MATISSE, suggesting that the region emitting in the thermal infrared is rather compact. An upper limit of mas (in…
Stellar Evolution and Tidal Dissipation in REBOUNDx
Stanley A. Baronett, Noah Ferich, Daniel Tamayo +1
To study the post-main sequence evolution of the Solar system and exoplanetary systems more accurately and efficiently, we introduce two new features to REBOUNDx, an extended libra…
Large-scale CO spiral arms and complex kinematics associated with the T Tauri star RU Lup
Jane Huang, Sean M. Andrews, Karin I. Öberg +9
While protoplanetary disks often appear to be compact and well-organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior…
A Study of Millimeter Variability in FUor Objects
John Wendeborn, Catherine C. Espaillat, Enrique Macias +6
FU Orionis objects (FUors) are rapidly-accreting, pre-main sequence objects that are known to exhibit large outbursts at optical and near-infrared wavelengths, with post-eruption,…
GW Ori: Interactions Between a Triple-star System and its Circumtriple Disk in Action
Jiaqing Bi, Nienke van der Marel, Ruobing Dong +17
GW Ori is a hierarchical triple system which has a rare circumtriple disk. We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 1.3 mm dust continuum and…
A triple star system with a misaligned and warped circumstellar disk shaped by disk tearing
Stefan Kraus, Alexander Kreplin, Alison K. Young +29
Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. The…
The Planetary Luminosity Problem: "Missing Planets" and the Observational Consequences of Episodic Accretion
Sean D. Brittain, Joan R. Najita, Ruobing Dong +1
The high occurrence rates of spiral arms and large central clearings in protoplanetary disks, if interpreted as signposts of giant planets, indicate that gas giants form commonly a…
Irregular dust features around intermediate-mass young stars with GPI: signs of youth or misaligned disks?
Anna S. E. Laws, Tim J. Harries, Benjamin R. Setterholm +14
We are undertaking a large survey of over thirty disks using the Gemini Planet Imager (GPI) to see whether the observed dust structures match spectral energy distribution (SED) pre…
