Eccentric Behavior of Eccentric Planets
Recent increases in the discovery of high multiplicity Sub-Jovian planetary systems, in addition to discoveries of giant planets of high eccentricities in these multiple body systems, lead to questions into their origins and evolution. The study of secular interactions is not new, however it has only recently been applied to exoplanetary systems. These systems sometimes fall far from the classi...
متن کاملHIGHLIGHTED TOPIC Eccentric Exercise Eccentric Exercise: Many questions unanswered
LOCOMOTION IS ARGUABLY one of the most ubiquitous and important manifestations of life, equally important to feeding as to escape predators. Evolution came up with three molecular motors to power motion: the actomyosin system Levitsky (11); the microtubule, dynein-based flagellar motors of eukaryotes (13); and the flagellar rotary motors of bacteria (15). All three systems serve propulsion, i.e...
متن کاملEccentric Connectivity Index
The eccentric connectivity index ξ is a novel distance–based molecular structure descriptor that was recently used for mathematical modeling of biological activities of diverse nature. It is defined as ξ(G) = ∑ v∈V (G) deg(v) · ε(v) , where deg(v) and ε(v) denote the vertex degree and eccentricity of v , respectively. We survey some mathematical properties of this index and furthermore support ...
متن کاملPhenomenology of eccentric fixation.
The purpose of this paper is to discuss the pathology and clinical features of limbal der moids and to illustrate these features with case records from the Wills Eye Hospital. A dermoid may be defined as a solid con genital tumor consisting of mesoblastic tis sue (fibrous and fatty usually) covered by ectoderm (skin) and invaded by ectodermal derivatives, that is, hair follicles, sebaceous a...
متن کاملEccentric Binary Millisecond Pulsars
In this paper we review recent discovery of millisecond pulsars (MSPs) in eccentric binary systems. Timing these MSPs we were able to estimate (and in one case precisely measure) their masses. These results suggest that, as a class, MSPs have a much wider range of masses (1.3 to > 2M⊙) than the normal and mildly recycled pulsars found in double neutron star (DNS) systems (1.25 < Mp < 1.44M⊙). T...
