X-ray Observations of the Peculiar Cepheid V473 Lyr Identify A Low-Mass Companion

Kavli Affiliate: Moritz Guenther | First 5 Authors: Nancy Remage Evans, Ignazio Pillitteri, Laszlo Molnar, Laszlo Szabados, Emese Plachy | Summary: V473 Lyr is a classical Cepheid which is unique in having substantial amplitude variations with a period of approximately 3.3 years, thought to be similar to the Blazhko variations in RR Lyrae stars. We […]

Resolving the FU Ori System with ALMA: Interacting Twin Disks?

Kavli Affiliate: David Principe | First 5 Authors: Sebastián Pérez, Antonio Hales, Hauyu Baobab Liu, Zhaohuan Zhu, Simon Casassus | Summary: FU Orionis objects are low-mass pre-main sequence stars characterized by dramatic outbursts of several magnitudes in brightness. These outbursts are linked to episodic accretion events in which stars gain a significant portion of their […]

Heliosheath Properties Measured from a Voyager 2 to Voyager 1 Transient

Kavli Affiliate: John D. Richardson | First 5 Authors: Jamie S. Rankin, David J. McComas, John D. Richardson, Nathan A. Schwadron, | Summary: In mid-2012, a GMIR observed by Voyager 2 crossed through the heliosheath and collided with the heliopause, generating a pressure pulse that propagated into the very local interstellar medium. The effects of […]

Characterisation of the Particle-Induced Background of XMM-Newton EPIC-pn: Short and Long Term Variability

Kavli Affiliate: Catherine Grant | First 5 Authors: Esra Bulbul, Ralph Kraft, Paul Nulsen, Michael Freyberg, Eric D. Miller | Summary: The particle-induced background of X-ray observatories is produced by Galactic Cosmic Ray (GCR) primary protons, electrons, and He ions. Events due to direct interaction with the detector are usually removed by on board processing. […]

Astro2020 APC White Paper: Providing a Timely Review of Input Demographics to Advisory Committees

Kavli Affiliate: Edmund Bertschinger | First 5 Authors: Dara Norman, Terri J. Brandt, Nancy D. Morrison, Sarah Tuttle, Julie Rathbun | Summary: Organizations that support science (astronomy) such as federal agencies, research centers, observatories, academic institutions, societies, etc. employ advisory committees and boards as a mechanism for reviewing their activities and giving advice on practices, […]

The structure of magnetic turbulence in the heliosheath region observed by Voyager 2 at 106 AU

Kavli Affiliate: John D. Richardson | First 5 Authors: Federico Fraternale, Nikolai V Pogorelov, John D Richardson, Daniela Tordella, | Summary: It is currently believed that the turbulent fluctuations pervade the outermost heliosphere. Turbulence, magnetic reconnection, and their link may be responsible for magnetic energy conversion in these regions. The governing mechanisms of such anisotropic […]

Magnetic turbulence spectra and intermittency in the heliosheath and in the local interstellar medium

Kavli Affiliate: John D. Richardson | First 5 Authors: Federico Fraternale, Nikolai V Pogorelov, John D Richardson, Daniela Tordella, | Summary: The understanding of inertial-scale dynamics in the heliosheath is not yet thorough. Magnetic field fluctuations across the inner heliosheath (IHS) and the local interstellar medium (LISM) are here considered to provide accurate and highly […]
