The subdwarf B star SB 290 - A fast rotator on the extreme horizontal branch

Hot subdwarf B stars (sdBs) are evolved core helium-burning stars with very thin hydrogen envelopes. In order to form an sdB, the progenitor has to lose almost all of its hydrogen envelope right at the tip of the red giant branch. In close binary systems, mass transfer to the companion provides the extraordinary mass loss required for their formation. However, apparently single sdBs exist as well and their formation is unclear since decades. The merger of helium white dwarfs leading to an ignition of core helium-burning or the merger of a helium core and a low mass star during the common envelope phase have been proposed. Here we report the discovery of SB 290 as the first apparently single fast rotating sdB star located on the extreme horizontal branch indicating that those stars may form from mergers.Comment: 5 pages, 4 figures, A&A letters, accepte

Gaussian Process models for ubiquitous user comfort preference sampling; global priors, active sampling and outlier rejection.

This paper presents a ubiquitous thermal comfort preference learning study in a noisy environment. We introduce Gaussian Process models into this field and show they are ideal, allowing rejection of outliers, deadband samples, and produce excellent estimates of a users preference function. In addition, informative combinations of users preferences becomes possible, some of which demonstrate well defined maxima ideal for control signals. Interestingly, while those users studied have differing preferences, their hyperparameters are concentrated allowing priors for new users. In addition, we present an active learning algorithm which estimates when to poll users to maximise the information returned

Strengthening socio-emotional learning in Aotearoa New Zealand: Teacher and whānau understanding of wellbeing

CAUL Read and Publish agreementInternational data provide evidence of the strong association between socio-emotional learning and wellbeing in students. However, while socio-emotional learning programmes are generally viewed as effective in developing socio-emotional capacities in students, culture is rarely considered within frameworks underpinning such programmes. In Aotearoa New Zealand, the high variability found in schools relating to approaches to develop wellbeing likely reflects universalistic conceptualisations of wellbeing and the low consideration for culture and language in socio-emotional learning. This indicates the need to develop a framework for socio-emotional learning that reflects the context of Aotearoa New Zealand. In the current article, we explore the socio-emotional understandings of teachers, and families and Māori whānau through wānanga and intentional noticing within a design-based research methodology to inform the development of a co-constructed framework for socioemotional learning. Crucial to socio-emotional learning were the relationships between students, teachers, families and Māori whānau across the learning pathway. Relationships were viewed as being underpinned by communication skills and holding understandings of emotions and emotional states. Overall, culture, language, and identity were viewed by as fundamental to wellbeing and should be at the fore of frameworks for socio-emotional learning, which should be localised within Indigenous understandings of wellbeing.fals

Weak magnetic fields in white dwarfs and their direct progenitors?

We have carried out a re-analysis of polarimetric data of central stars of planetary nebulae, hot subdwarfs, and white dwarfs taken with FORS1 (FOcal Reducer and low dispersion Spectrograph) on the VLT (Very Large Telescope), and added a large number of new observations in order to increase the sample. A careful analysis of the observations using only one wavelength calibration for the polarimetrically analysed spectra and for all positions of the retarder plate of the spectrograph is crucial in order to avoid spurious signals. We find that the previous detections of magnetic fields in subdwarfs and central stars could not be confirmed while about 10% of the observed white dwarfs have magnetic fields at the kilogauss level.Comment: 6 pages, Proceedings of the 18th European White Dwarf Workshop, ASP Conference Serie
