What can be a star, an oil, and a type of wheel?
Oil cleansing method Oil cleansing method The oil cleansing method, often abbreviated as OCM, is a system for cleaning a human face using oil(s). Sometimes, oils can be mixed; one example is 50% extra virgin olive oil and 50% castor oil. This mixture can be optimized based on skin type and personal preference. In accordance with skin type variations, castor oil may be too harsh in some skin-care regimens and is sometimes used in a 1:9 ratio. However, overly oily skin can make use of a larger proportion of castor oil. Other oils that are commonly used are jojoba oil, sweet almond oil,
A-type main-sequence star also occasionally sees Delta Leonis (A4 V) listed as a standard. There are no published A6 V and A8 V standard stars. A-type stars are young (typically few hundred million years old) and many emit infrared (IR) radiation beyond what would be expected from the star alone. This IR excess is attributable to dust emission from a debris disk where planets form. Surveys indicate massive planets commonly form around A-type stars although these planets are difficult to detect using the Doppler spectroscopy method. This is because A-type stars typically rotate very quickly, which makes it difficult to measure the small
