title = "Evidence for pulsation-driven mass loss from ı cephei",
abstract = "We found the first direct evidence that the Cepheid class namesake, ı Cephei, is currently losing mass. These observations are based on data obtained with the Spitzer Space Telescope in the infrared, and with the Very Large Array in the radio. We found that ı Cephei is associated with a vast circumstellar structure, reminiscent of a bow shock. This structure is created as the wind from the star interacts with the local interstellar medium. We measure an outflow velocity of ≈ 35:5 km s-1 and a mass loss rate of ≈ 10-7 –10-6 Mͽ year-1. The very low dust content of the outflow suggests that the wind is possibly pulsation-driven, rather than dust-driven as common for other classes of evolved stars.",
