The following is a progress report on the long-term coronal (T ∼ 1 MK) activity of α Centauri A (HD 128620: G2 V) and B (HD 128621: K1 V). Since 2005, Chandra X-Ray Observatory has carried out semiannual pointings on AB, mainly with the High Resolution Camera, but also on two occasions with the Low-Energy Transmission Grating Spectrometer, fully resolving the close pair in all cases. During 2008–2013, Chandra captured the rise, peak, and initial decline of B's coronal luminosity. Together with…

THE FAR-ULTRAVIOLET UPS AND DOWNS OF ALPHA CENTAURI

Four years (2010–2014) of semiannual pointings by the Hubble Space Telescope Imaging Spectrograph (STIS) on nearby Alpha Centauri have yielded a detailed time history of far-ultraviolet (FUV:

For more than a decade, Alpha Centauri AB (G2 V+K1 V) has been observed by Chandra, in a long-term program to follow coronal (T ∼ 106 K) activity cycles of the two sunlike stars. Over 2008.4–2017.8,

Optical, UV, and X-ray evidence for a 7-yr stellar cycle in Proxima Centauri

Stars of stellar type later than about M3.5 are believed to be fully convective and therefore unable to support magnetic dynamos like the one that produces the 11-year solar cycle. Because of their

ALMA observations of α Centauri - First detection of main-sequence stars at 3 mm wavelength

Context. The precise mechanisms that provide the non-radiative energy for heating the chromosphere and the corona of the Sun and those of other stars constitute an active field of research. By

Multi-wavelength variability of the young solar analog ι Horologii

Context. Chromospheric activity cycles are common in late-type stars; however, only a handful of coronal activity cycles have been discovered. ι Hor is the most active and youngest star with known

The radii and limb darkenings of α Centauri A and B . Interferometric measurements with VLTI/PIONIER

The photospheric radius is one of the fundamental parameters governing the radiative equilibrium of a star. We report new observations of the nearest solar-type stars α  Centauri A (G2V) and B (K1V)

Detection of α Centauri at radio wavelengths: chromospheric emission and search for star–planet interaction

At radio wavelengths, solar type stars emit thermal free-free and gyroresonance, gyrosynchrotron, and impulsive coherent emission. Thermal free-free emission originates at layers where the optical

A SEARCH FOR CORONAL ACTIVITY AMONG TWO METAL-POOR SUBDWARFS AND ONE SUBGIANT

A search has been made using the XMM-Newton satellite for coronal soft X-ray emission from HD 19445, HD 25329, and HD 140283, three Population II stars in the Galactic halo having metallicities of .

Fifteen years in the high-energy life of the solar-type star HD 81809. XMM-Newton observations of a stellar activity cycle

Aims. The data set of the long-term XMM-Newton monitoring program of HD 81809 is analyzed to study its X-ray cycle, to investigate if the latter is related to the chromospheric one, to infer the

Coronal X-ray emission and planetary irradiation in HD 209458

HD 209458 is one of the benchmark objects in the study of hot Jupiter atmospheres and their evaporation through planetary winds. The expansion of the planetary atmosphere is thought to be driven by

The Fainting of α Centauri A, Resolved

Beginning in 2003, XMM-Newton snapshot monitoring of α Centauri (HD 128620, 128621: G2 V, K1 V) documented a steady fading of the primary’s X-ray corona, which had all but disappeared by early 2005.

THE CYCLES OF α CENTAURI

The main AB pair of the nearby α Centauri triple system has one of the most extensive X-ray records of any cosmic object, stretching over 30 years. The primary, α Cen A (G2 V), is a near twin of the

The Chandra X-Ray Observatory has detected coronal (T ≳ 106 K) emission from the red giant γ Draconis (HD 164058: K5 III; d = 45 pc), now fully resolved from a stronger source 21'' to the SE that had
