Interferometric view of the circumstellar envelopes of northern FU Orionis-type stars
O. Fehér, Á. Kóspál, P. Ábrahám +2
FU Orionis-type objects are young, low-mass stars with large outbursts in visible light that last for several years or decades. They are thought to represent an evolutionary phase…
Orbital advection with magnetohydrodynamics and vector potential
Wladimir Lyra, Colin P. McNally, Tobias Heinemann +1
Orbital advection is a significant bottleneck in disk simulations, and a particularly tricky one when used in connection with magnetohydrodynamics. We have developed an orbital adv…
Mass transport from the envelope to the disk of V346 Nor: a case study for the luminosity problem in an FUor-type young eruptive star
Á. Kóspál, P. Ábrahám, T. Csengeri +7
A long-standing open issue of the paradigm of low-mass star formation is the luminosity problem: most protostars are less luminous than theoretically predicted. One possible soluti…
Tweaking one-loop determinants in AdS
Alejandra Castro, Cynthia Keeler, Phillip Szepietowski
We revisit the subject of one-loop determinants in AdS gravity via the quasinormal mode method. Our goal is to evaluate a one-loop determinant with chiral boundary conditions f…
Damping of gravitational waves by matter
Gordon Baym, Subodh P. Patil, C. J. Pethick
We develop a unified description, via the Boltzmann equation, of damping of gravitational waves by matter, incorporating collisions. We identify two physically distinct damping mec…
Structure and mass segregation in Galactic stellar clusters
Sami Dib, Stefan Schmeja, Richard J. Parker
We quantify the structure of a very large number of Galactic open clusters and look for evidence of mass segregation for the most massive stars in the clusters. We characterise the…
