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.

SWSex Stars, Old Novae, and the Evolution of Cataclysmic Variables
Acta Polytechnica CTU Proceedings, 2015 The population of cataclysmic variables with orbital periods right above the period gap are dominated by systems with extremely high mass transfer rates, the so-called SW Sextantis stars.

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.

Wildlife Letters, EarlyView.Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

Systematics of Dwarf Novae [PDF]
Astrophysics and Space Science, 1987 AbstractFrom about 30 Dwarf Novae with the best determined distances the following relationships are found.(i)a tight correlation between absolute magnitude at maximum light, Mv (max), and orbital period, P.(ii)a correlation between Mv (min) and P showing wide scatter.(iii)a correlation between Mv (mean), the mean absolute magnitude averaged over ...

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.

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 ...

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
