Kavli Affiliate: David A. Principe | First 5 Authors: Anastasiia V Uvarova, Hans Moritz Günther, David A. Principe, P. Christian Schneider, | Summary: Young stars accrete mass and angular momentum from their circumstellar disks. Some of them also drive outflows, which can be distinguished in optical forbidden emission lines (FELs). We analyze a sample of […]
Kavli Affiliate: Christopher Burke | First 5 Authors: Ryan Cloutier, Jason D. Eastman, Joseph E. Rodriguez, Nicola Astudillo-Defru, Xavier Bonfils | Summary: We present the confirmation of two new planets transiting the nearby mid-M dwarf LTT 3780 (TIC 36724087, TOI-732, $V=13.07$, $K_s=8.204$, $R_s$=0.374 R$_{odot}$, $M_s$=0.401 M$_{odot}$, d=22 pc). The two planet candidates are identified in […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Jeroen Homan, Joe Bright, Sara E. Motta, Diego Altamirano, Zaven Arzoumanian | Summary: We present Neutron Star Interior Composition Explorer X-ray and Arcminute Microkelvin Imager Large Array radio observations of a rapid hard-to-soft state transition in the black hole X-ray transient MAXI J1820+070. During the transition […]
Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: The Gopakumar-Vafa type invariants on Calabi-Yau 4-folds (which are non-trivial only for genus zero and one) are defined by Klemm-Pandharipande from Gromov-Witten theory, and their integrality is conjectured. In a previous work of Cao-Maulik-Toda, $mathrm{DT}_4$ invariants with primary insertions […]
