Abstract We systematically surveyed period variations of superhumps in SU UMa-type dwarf novae based on newly obtained data and past publications. In many systems, the evolution superhump is found to be composed three distinct stages: an early evolutionary stage with a longer period, middle varying periods, final shorter, stable period. During stage, systems periods less than 0.08 d show positive derivatives. present observational characteristics these stages give greatly improved...
There has been extensive work in the space of Indigenous epistemological approaches to research. Because Australian peoples have researched significantly, there are guidelines around ethical and cultural conduct this type Via investigating Academy's approach research general, we can illuminate vast differences between empirical from 'West' compared knowledge acquisition sharing through 'relationality' an perspective. This paper investigates dichotomy brings into question premise power value...
As one approach to moving beyond transmitting "inert" ideas chemistry students, we use the term "teaching from rich contexts" describe implementations of case studies or context-based learning based on systems thinking that provide deep and opportunities for crosscutting concepts through contexts. This nurtures higher-order cognitive skills connect apply knowledge gained new We used design a set resources model how contexts can be facilitate general topics. The Visualizing Chemistry Climate...
We summarize the results of a 20-yr campaign to study light curves BK Lyn, nova-like star strangely located below 2 3 h orbital-period gap in family cataclysmic variables (CVs). Two apparent superhumps dominate nightly curves, with periods 4.6 per cent longer, and 3.0 shorter, than orbital period. The first appears be associated star's brighter states (V ∼ 14), while second present throughout becomes very dominant low state 15.7). It is plausible that these arise, respectively, from prograde...
Quality assessment of facial images differs from the traditional quality image and video signals with regards to its multiple goals such as ensure fidelity human visual system (HVS) model, predict matching performance, generate feedback on acquisition, guard enrollment process, provide a weight for merging multimodal biometrics. In this paper, we present framework that complies requirements ISO/IEC 19794-5 biometrics additionally ensures optimal recognition performance. This employs novel...
The design and implementation of an inexpensive, high-resolution Littrow-type visible light spectrometer is presented. instrument built from low-cost materials interfaced with the program RSpec for real-time spectral analysis, making it useful classroom laboratory exercises. Using a diffraction grating ruled at 1200 lines/mm blazed in first order, was found to have resolution (R = λ/Δλ) 7500 (0.07 nm) 525 nm allowing detailed spectroscopic experiments such as analysis iodine vibronic...
Climate change is one of the most critical problems facing citizens today. Chemistry faculty are presented with problem making general chemistry content simultaneously relevant and interesting. Using climate science to teach allows help students learn in a rich context. Concepts related electromagnetic radiation gases can be taught using an understanding how greenhouse work. However, it would important know level prior knowledge that bring course their confidence knowledge. Thus, two-tiered...
Global science is paying increasingly urgent attention to sustainability challenges, as evidenced by initiatives such the working group determining whether Earth has moved from Holocene Anthropocene Epoch on geologic time scale and interdisciplinary efforts define quantify our planetary boundaries. Despite fact that much of scientific work underlying these based measurements fundamental chemistry parameters, literacy not been incorporated in any systematic way into undergraduate curriculum....
Abstract We report here on time-resolved photometric observations of the superoutburst a dwarf nova, RZ Leo, which occurred during 2000 December–2001 January. reveal following characteristics outburst based our observations: long duration, large amplitude, and existence two types superhumps — “early superhumps” “normal superhumps”. In addition to extremely low frequency outbursts, strongly indicate that Leo is fifth member WZ Sge-type novae. The orbital period 0.07651 d, remarkably longer...
Theoretical hydrogen line and continuum spectra are computed for magnetic white dwarfs a range of parameters assuming centred off-centred field distributions. The results compared with the observations three known DA GD 90, G 99-47 BPM 25114. We find that in each case, or dipole model can be found which gives reasonable agreement available spectrophotometric data, circular polarization data spectropolarimetric data. In particular, contrary to conclusions some previous investigators, we no...
An analytical solution method is presented for the problem of radiative transfer in presence a magnetic field and absorbing lines. Previously available methods are also tested, usefulness limitations different discussed.
Being Indigenous and operating in an institution such as a university places us complex position. The premise of decolonizing history, literature, curriculum, thought general creates tenuous space for non-Indigenous peoples to confront shared colonial condition. What does decolonization mean peoples? Is implied promise squash the tropes coloniality? Or is it way people create another paradigm or site their own resistance transgression thinking? are roles this educational potential,...
This article explores research that was undertaken in a PhD project investigated the creation and effectiveness of Critical Co-Design as methodology. In particular, it how this methodology enabled successful outcomes from workshop conducted with young Indigenous Australian women. The aimed to create platform for researcher work alongside peoples Australia order mutually beneficial ways working. Here, authors reflect upon postulate importance privileging knowing way shifting approaches design...
We present an analysis of photometric observations the eclipsing novalike variable DW UMa made by CBA consortium between 1999 and 2015. Analysis 372 new 260 previously published eclipse timings reveals a 13.6 yr period or quasi-period in times minimum light. The seasonal light curves show complex spectrum periodic signals: both positive negative 'superhumps', likely arising from prograde apsidal precession retrograde nodal accretion disc. These signals appear most prominently famously as...
An intensive photometric-observation campaign of the recently discovered SU UMa-type dwarf nova, Var73 Dra was conducted from 2002 August to 2003 February. We caught three superoutbursts in October, December and The recurrence cycle superoutburst (supercycle) is indicated be ~60 d, shortest among values known so far UMa stars close those ER stars. superhump periods measured during first two were 0.104885(93) 0.10623(16) respectively. A 0.10424(3)-d periodicity detected quiescence. change...
We show that spectroscopic observations of the magnetic white dwarf in AM Herculis obtained 1979 when system was a low state indicate field geometry is different from centred dipole. A model based on an offset dipole gives reasonable agreement with and suggests at accreting pole may be significantly lower (∼ 1.4 × 107 G) than has previously been assumed.
