Coronal activity cycles in action - X-rays from alpha Centauri A/B We report on the coronal activity cycles of our stellar neighbors alpha Centauri A/B. The binary has been monitored with XMM-Newton since 2002 to study the... J Robrade,JHMM Schmitt 被引量: 6发表: 2016年 Burst phenomen...
HST/ACS IMAGING OF OMEGA CENTAURI: OPTICAL COUNTERPART FOR THE QUIESCENT LOW-MASS X-RAY BINARY1 We report the discovery of an optical counterpart to a quiescent neutron star in the globular cluster Omega Centauri (NGC 5139). The star was found as part... D Haggard,AM Cool,J Anderson,.....
which are called “detector persistence.” 3 is an “optical ghost” of Alpha Centauri A. Panel (b) on the right is a zoom-in on the inner regions of the (a) image. The candidate exoplanet is labelled as C1. Image Credit: Wagner et al, 2021. ...
stars: individual: α Centauriplanetary systems: formationRecent studies have shown that alpha Centauri B might be, from an observational point of view, an ideal candidate for the detection of an Earth-like planet in or near its habitable zone (0.5-0.9AU). We study here if such habitable...
When the crew of the Defiant in 2371 scanned for Federation and alien outposts, all they could find were Romulan transmissions detected in the vicinity of Alpha Centauri. (DS9: "Past Tense, Part I") In the anti-time future, Romulus had not been destroyed by a supernova, but the ...
Alpha Centauri stands as the closest known stellar system to our Solar System at a distance of 1.34 pc away from Earth [1]. As such, it constitutes a target of choice for numerous studies related to stellar and orbit characterisation, e.g., [2,3,4]. This system is composed of three ...
Alpha Centauri is the closest star system to Earth and is made up of three stars and several exoplanets. We explore our stellar neighbors in more detail here.
