Evolution of brightness and magnetic features of young solar-type stars II: The young F8 star HIP 71933

Autor: J E Hughes, S C Marsden, B D Carter, I A Waite, D M Burton, G M Perugini, E M Hébrard

Publikováno v: Monthly Notices of the Royal Astronomical Society.

The early, active history of our Sun is still not fully understood. Observations of the magnetic fields on active young solar-type stars allows us an insight into the early evolution of our Sun. Here we present Doppler and Zeeman Doppler images of th

The evolution in latitude of sunspots is a key feature of the cyclic solar dynamo. Here, we present the results of a spectroscopic and spectropolarimetric monitoring campaign on the young (∼20 Myr old) early G star HIP 89829, in order to investigat

Underwater noise from submarine turbidity currents

Autor: Matthew Hatcher, Alex E. Hay, J. E. Hughes Clarke

Publikováno v: JASA express letters. 1(7)

Noise from turbidity currents flowing down the face of a fjord delta was measured underwater at frequencies from 1 to 1200 kHz. The noise spectra are consistent with sound generation by collisions among sand-sized particles. The spectra from the lead

International audience; Glacier and ice sheet mass loss as a result of climate change is driving important coastal changes in Arctic fjords. Yet limited information exists for Arctic coasts regarding the influence of glacial erosion and ice mass loss

ObjectiveThe mechanistic target of rapamycin complex 1 (mTORC1) is dynamically regulated by fasting and feeding cycles in the liver to promote protein and lipid synthesis while suppressing autophagy. However, beyond these functions, the metabolic res

Turbidity currents are powerful flows of sediment that pose a hazard to critical seafloor infrastructure and transport globally important amounts of sediment to the deep sea. Due to challenges of direct monitoring, we typically rely on their deposits

Which triggers produce the most erosive, frequent and longest runout turbidity currents on deltas?

Publikováno v: Geophysical research letters, 2018, Vol.45(2), pp.855-863 [Peer Reviewed Journal]

Subaerial rivers and turbidity currents are the two most voluminous sediment transport processes on our planet, and it is important to understand how they are linked offshore from river mouths. Previously it was thought that slope failures or direct
