These Sun-like stars have well-determined cyclic flux variations similar to 11 yr solar activity cycle. Our flux prediction is based on chromospheric HK emission time series measurements from Mount Wilson Observatory and comparable solar data. We show that solar three - component modeling explains well the stellar observations. We find that the 10 - 20% of K - stars disc surfaces are occupied by bright active regions.", "revisions": [ { "version": "v1", "updated": "2010-12-22T19:36:00.000Z" } ], "analyses": { "keywords": [ "main-sequence stars", "chromospheric variations modeling", "cyclic flux variations similar", "spectral classes", "chromospheric hk emission time series" ], "tags": [ "journal article" ], "publication": { "doi": "10.1080/10556790410001666319", "journal": "Astronomical and Astrophysical Transactions", "year": 2004, "month": "Feb", "volume": 23, "number": 2, "pages": 165 }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 882115, "adsabs": "2004A&AT...23..165B" } } }
