A5_4 Burning Giants

In this article we aim to investigate the plausibility of using a neutron star to raise the mass ofa gas giant to the point where fusion reactions will begin to take place, creating a star. We shallalso determine if this could be used to produce additional habitable planets in our Solar Systemby this method. We nd that while a neutron star can turn Jupiter into a small star it will notproduce any new planets in the habitable zone

A5_3 Sliding in Space

This paper is based on a thought experiment in which the scenario 'How long would it take a person to go down a slide from the Moon to Earth?' is addressed. After making various assumptions to simplify this experiment, the time taken was calculated to be 74 hours

A5_5 How big are the planets, really?

In this paper, we investigate the discrepancies in circumference of the planets in the Solar System that arise due to relativistic length contraction caused by their angular velocities. We then compare these discrepancies with the aim of creating a new method of comparison for different celestial bodie

SOFIA and ALMA Investigate Magnetic Fields and Gas Structures in Massive Star Formation: The Case of the Masquerading Monster in BYF 73

We present SOFIA+ALMA continuum and spectral-line polarisation data on the massive molecular cloud BYF 73, revealing important details about the magnetic field morphology, gas structures, and energetics in this unusual massive star formation laboratory. The 154$\mu$m HAWC+ polarisation map finds a highly organised magnetic field in the densest, inner 0.55$\times$0.40 pc portion of the cloud, compared to an unremarkable morphology in the cloud's outer layers. The 3mm continuum ALMA polarisation data reveal several more structures in the inner domain, including a pc-long, $\sim$500 M$_{\odot}$ "Streamer" around the central massive protostellar object MIR 2, with magnetic fields mostly parallel to the east-west Streamer but oriented north-south across MIR 2. The magnetic field orientation changes from mostly parallel to the column density structures to mostly perpendicular, at thresholds $N_{\rm crit}$ = 6.6$\times$10$^{26}$ m$^{-2}$, $n_{\rm crit}$ = 2.5$\times$10$^{11}$ m$^{-3}$, and $B_{\rm crit}$ = 42$\pm$7 nT. ALMA also mapped Goldreich-Kylafis polarisation in $^{12}$CO across the cloud, which traces in both total intensity and polarised flux, a powerful bipolar outflow from MIR 2 that interacts strongly with the Streamer. The magnetic field is also strongly aligned along the outflow direction; energetically, it may dominate the outflow near MIR 2, comprising rare evidence for a magnetocentrifugal origin to such outflows. A portion of the Streamer may be in Keplerian rotation around MIR 2, implying a gravitating mass 1350$\pm$50 M$_{\odot}$ for the protostar+disk+envelope; alternatively, these kinematics can be explained by gas in free fall towards a 950$\pm$35 M$_{\odot}$ object. The high accretion rate onto MIR 2 apparently occurs through the Streamer/disk, and could account for $\sim$33% of MIR 2's total luminosity via gravitational energy release.Comment: 33 pages, 32 figures, accepted by ApJ.

Knowledge, Attitudes, Beliefs and Behaviors Regarding Fruits and Vegetables among Cost-Offset Community-Supported Agriculture (CSA) Applicants, Purchasers, and a Comparison Sample

Data were collected in August, amid the summer CSA season, when shares include many of the summer FV preferred by low-income caregivers and their children [33], which may have contributed to the magnitude of the differences in children’s FV consumption that we observed. Because resources to support the CO-CSA were limited and offsets were awarded on a first-come first-served basis, and because almost all KABs were equivalent for purchaser and non-purchaser sub-groups, selection bias into the purchaser sub-group is an unlikely explanation for differences observed between CO-CSA purchasers and non-purchasers. [...]the inclusion of some CO-CSA applicants who participated in a longitudinal study regarding CO-CSA may have biased upwards estimates of KAB and self-efficacy with respect to FV consumption in the applicant sample. [...]although selection of adults into the comparison group used similar eligibility criteria, they were not comparable to CO-CSA applicants who were older, more educated, and more often lived in food-secure households. [...]sample sizes were too small to permit exploration of observed associations in a multivariate context that controlled for key sample differences such as age, educational attainment, or self-efficacy for eating and cooking FV. 5

Gaining and maintaining a competitive edge: Evidence from CSA members and farmers on local food marketing strategies

Community-supported agriculture (CSA) is a widely-used approach for farmers to sell directly to consumers. We used the product, place, price, and promotion (4P) marketing mix framework to examine characteristics that help farms offering CSA maintain member satisfaction and thus competitiveness. We conducted semi-structured interviews with 20 CSA members and 24 CSA farmers in four states. CSA members additionally completed a modified choice experiment. Qualitative data were coded iteratively, and choice experiment data were summarized and compared across scenarios. CSA members and farmers were motivated by a range of personal, social, environmental, and economic objectives. Members favored high-quality staple vegetables (e.g., lettuce, green beans), ideally produced organically. Trust and a sense of personal connection with the farmer comprised part of the value added of CSA participation. Time and location of share pick-up were very important; thus, farmers tried to offer convenient sites or an enriched pick-up experience. Small changes in price appeared unlikely to impact participation among current members. Social networks and word-of-mouth were powerful for marketing, but may limit the ability to reach diverse populations. Future research should examine the ability of CSAs to meet the needs of those who do not currently participate
