A Transient Radio Jet in an Erupting Dwarf Nova [PDF]
Science, 2008 Astrophysical jets seem to occur in nearly all types of accreting objects, from supermassive black holes to young stellar objects. On the basis of x-ray binaries, a unified scenario describing the disc/jet coupling has evolved and been extended to many accreting objects.

Ecological Entomology, EarlyView.We used iNaturalist records, a longitudinal field survey, and a simulated herbivory experiment to explore how insect herbivory factors are associated with Cornus canadensis fruit production. Naturally observed internal and external insect herbivory was mostly low intensity and did not have a strong relationship with fruit production.

Observations of Dwarf Novae [PDF]
Symposium - International Astronomical Union, 1976 Spectroscopic and photometric observations relevant to the structure of classical novae, recurrent novae and dwarf novae are collected together. Details are given of optical, infrared, satellite ultraviolet, X-ray and radio observations. Most of these can be understood in terms of the hot spot model of cataclysmic variable stars.

Hot white dwarfs and the UV delay in dwarf novae [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We calculate the effect of illumination of dwarf nova accretion discs by radiation from a hot, central, white dwarf. We show that only for very hot white dwarfs (Teff ~ 40 000$ K) the inner region of quiescent dwarf nova discs are partially depleted so that the delay between the rise to outburst of the optical and UV fluxes would be increased as ...

International Journal of Art &Design Education, EarlyView.Abstract This autoethnographic study lies at the intersection of architectural, teaching and research practice through the lens of an architect‐teacher‐researcher working in post‐Apartheid South Africa. The research traces a shift from unconscious design practice to a more conscious, critical and careful practice through practice‐based design research ...

, 1993 Dwarf novae are defined on grounds of their semi-regular brightness variations of some two to five magnitudes on time scales of typically 10 to 100 days. Historically several different classification schemes have been used. Today, dwarf novae are divided

JCMS: Journal of Common Market Studies, EarlyView.Abstract In recent years, the European Union (EU) expanded its digital regulatory competences. However, it is not clear which political trade‐offs occur in decision‐making on digital policy issues. This study examines how European parliamentarians and their party groups position themselves on these issues and which conflict lines emerge. Analysing roll

Radiation from dwarf nova discs
Physics Reports, 1999 We use the Shaviv and Wehrse (1991) code to model the vertical structure and the emission properties of quiescent dwarf nova discs. We find that in the case of HT Cas the quiescent disc must be optically thin, in contradiction with the requirements of the standard disc instability model. We find a viscosity parameter alpha > 1. Although this is much

The Astrophysical JournalWe present 120 s cadence TESS observations of three superoutbursts of the SU UMa-type dwarf nova VW Hydri. Two events (SO2 in Sectors 87+88 and SO3 in Sector 93) exhibit a temporally pronounced precursor dip followed by a rapid rise into the main ...
