How Solar Soft X-Ray Irradiance Is Affected by the Size of Field of View
The Astrophysical Journal, 2023 Soft X-ray images of the Sun obtained with multiple broadband filters provide a simple and useful method to calculate averaged coronal temperature and emission measure, from which we can further calculate solar X-ray irradiance in physical units, e.g ...

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59
Astronomische Nachrichten, EarlyView.ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

HINODE X-RAY TELESCOPE DETECTION OF HOT EMISSION FROM QUIESCENT ACTIVE REGIONS: A NANOFLARE SIGNATURE? [PDF]
, 2009 The X-Ray Telescope (XRT) on the Japanese/USA/UK Hinode (Solar-B) spacecraft has detected emission from a quiescent active region core that is consistent with nanoflare heating. The fluxes from 10 broadband X-ray filters and filter combinations were used

The behavior of subluminous X-ray transients near the Galactic center as observed using the X-ray telescope aboard Swift [PDF]
, 2008 In this paper we report on the spectral analysis of seven X-ray transients, which were found to be active during a monitoring campaign of the Galactic center carried out in 2006 and 2007 using the X-ray telescope aboard the Swift satellite. This campaign

Chemistry – A European Journal, EarlyView.44 novel heterocycle fragments are prepared through a C–H functionalization strategy. Systematic variation of exit vectors and polar functionality provides a set of fragments that sit in attractive fragment chemical space. Abstract Saturated heterocycles are valuable fragments in drug discovery due to their polarity, 3D structure, and potential for ...
