     "Let's narrow down the search to one particular star: cepheid variable \"V1154-Cyg\". Cepheid Variables are pulsating stars, which physically grow larger and smaller, and as a result brighter and dimmer, on a regular rhythm of few days. Cepheid variables in particular are useful to study in astronomy because their pulsation period correlates with their intrinsic brightness, making it easy to determine how far away the star is! Later in this notebook, we will look at some other kinds of variable stars.\n",
