We present an independent discovery and detailed characterization of K2-280 b, a transiting low density warm sub-Saturn in a 19.9-d moderately eccentric orbit (e = 0.35 -0.04+0.05) from K2 campaign 7. A joint analysis of high precision HARPS, HARPS-N, and FIES radial velocity measurements and K2 photometric data indicates that K2-280 b has a radius of Rb = 7.50 ± 0.44 R⊕ and a mass of Mb = 37.1 ±

A significant fraction of an exoplanet transit model evaluation time is spent calculating projected distances between the planet and its host star. This is a relatively fast operation for a circular orbit, but slower for an eccentric one. However, because the planet's position and its time derivatives are constant for any specific point in orbital phase, the projected distance can be calculated ra

Childhood poverty increases the likelihood of being poor as an adult. We know relatively little about this persistence of poverty in the past and whether it changed as modern welfare societies developed. This study both analyses determinants of childhood poverty and assesses the association between childhood poverty and economic outcomes in adulthood for men and women who grew up in southern Swede

We report the discovery of a planetary system orbiting TOI-763(aka CD-39 7945), a V = 10.2, high proper motion G-type dwarf star that was photometrically monitored by the TESS space mission in Sector 10. We obtain and model the stellar spectrum and find an object slightly smaller than the Sun, and somewhat older, but with a similar metallicity. Two planet candidates were found in the light curve t

Grounded in social exchange theory (SET) this paper presents research on non-collaborative behaviour among accommodation businesses within their spatial context. The study adopts semi-structured interviews of 14 co-located accommodation businesses in Christchurch, New Zealand. The findings reveal three categories of non-collaborative factors that influence business behaviour, namely (1) resource-b

For the class of de Branges-Rovnyak spaces H(b) of the unit disk D defined by extreme points b of the unit ball of H∞, we study the problem of approximation of a general function in H(b) by a function with an extension to the unit circle T of some degree of smoothness, for instance satisfying Hölder estimates or being differentiable. We will exhibit connections between this question and the theory

Background: Takotsubo syndrome (TS) is a life-threatening acute heart failure syndrome without any evidence-based treatment options. No treatment for TS has been examined in a randomized trial. Study design and objectives: BROKEN-SWEDEHEART is a multicenter, randomized, open-label, registry-based 2 × 2 factorial clinical trial in patients with TS designed to test whether treatment with adenosine a

This open access book offers a detailed study of the foundation and expansion of the Dutch Cape Colony to ask why certain regions in the global south became European settler societies from the 16th century onwards.Examining the different factors that led to the creation of the Cape Colony, Erik Green reveals it was a gradual process, made up of ad hoc decisions, in which the agency of indigenous p

Appropriate evaluation and experimental design are fundamental for empirical sciences, particularly in data-driven fields. Due to the successes in computational modeling of languages, for instance, research outcomes are having an increasingly immediate impact on end users. As the gap in adoption by end users decreases, the need increases to ensure that tools and models developed by the research co
