Giant tidal tails of helium escaping the hot Jupiter HAT-P-32 b.

Capturing planets in the act of losing their atmospheres provides rare opportunities to probe their evolution history. This analysis has been enabled by observations of the helium triplet at 10,833 angstrom, but past studies have focused on the narrow time window right around the planet's optical transit. We monitored the hot Jupiter HAT-P-32 b using high-resolution spectroscopy from the Hobby-Eberly Telescope covering the planet's full orbit.

Clinical characteristics and progression of COVID-19 confirmed cases admitted to a single British clinical centre-A brief case series report.

Objectives: In December 2019, a pneumonia-like illness was first reported in Wuhan-China caused by a new coronavirus named corona virus disease-2019 (COVID-19) which then spread to cause a global pandemic. Most of the available data in the literature is derived from Chinese cohorts and we aim to contribute the clinical experience of a single British clinical centre with the characteristics of a British cohort.

Design: A prospective case series.

Characteristics of patients with diabetes hospitalised for COVID-19 infection-a brief case series report.

Objectives: Diabetes has been shown to be a risk factor for corona virus disease-2019 (COVID-19) infection. The characteristics of patients with diabetes vulnerable to this infection are less specified. We aim to present the characteristics of patients with diabetes admitted to hospital with COVID-19.

Chinese and British Hospitalised Patients with COVID-19-a Comparative Case Series Analysis.

The COVID-19 pandemic initially started in China then spread to Europe. It is not known whether COVID-19 affects patients differently across the two continents. We aimed to describe our cohort of patients admitted to a single British centre with COVID-19 in comparison to a Chinese cohort of similar size and admitted over a similar time period to Chinese centres.

Helium in the eroding atmosphere of an exoplanet.

Helium is the second-most abundant element in the Universe after hydrogen and is one of the main constituents of gas-giant planets in our Solar System. Early theoretical models predicted helium to be among the most readily detectable species in the atmospheres of exoplanets, especially in extended and escaping atmospheres . Searches for helium, however, have hitherto been unsuccessful .
