title = "On the origin of the {"}kleine K{\"u}gelchen{"} called Chondrules",
abstract = "In this paper we investigate two major issues: (1) What are chondrules, and (2) why do they exist? We review the literature pertaining to each question and explore answers. We discuss the diversity of chondrules, especially with regard to their igneous textures and compositions. We review the constraints that have been placed experimentally on the thermal histories of chondrules and list those fundamental properties that all chondrule formation models must explain quantitatively in order to be considered predictive, quantitative models. We provide background on the three major classes of chondrule formation models currently being discussed, and scrutinize each with respect to how well they adhere to the experimental constraints placed on chondrule formation. Finally, we list several unresolved issues that are now or will soon be at the forefront of chondrule research.",

note = "Funding Information: We thank K. Keil for his most gracious invitation to write this paper and for his patience during the writing process. He has been most kind. We thank J. Wood and P. Cassen for their unwavering efforts in looking at the big picture and keeping the finest details aligned to this process. They have motivated us time and time again to reflect upon what we are doing and why. We are also grateful to R. Hewins and G. Lofgren for inspiring us to understand chondrules by combining experimental data with modeling. They have been leaders within this field and we are honored to have worked with them in various ways and to have learned from and with them. All the images of chondrules were taken from the collection of the American Museum of Natural History, and we are grateful to D. Ebel for loan of the sections for imaging and to M. Weisberg for his help. The writing of this paper was supported in part by a grant from PSC-CUNY foundation, Grant # 65253-00 34, H. C. Connolly Jr. P.I. ",
