As part of our on-going investigation into the magnetic field properties of ultracool dwarfs, we present simultaneous radio, X-ray, and Hα observations of three M9.5-L2.5 dwarfs (BRI 0021-0214, LSR 060230.4+391059, and 2MASS J052338.2−140302). We do not detect X-ray or radio emission from any of the three sources, despite previous detections of radio emission from BRI 0021 and 2M0523−14. Steady and variable Hα emission are detected from 2M0523−14 and BRI 0021, respectively, while no Hα emission is detected from LSR 0602+39. Overall, our survey of nine M8-L5 dwarfs doubles the number of ultracool dwarfs observed in X-rays, and triples the number of L dwarfs, providing in addition the deepest limits to date, log(L X /L bol ) −5.With this larger sample we find the first clear evidence for a substantial reduction in X-ray activity, by about two orders of magnitude, from mid-M to mid-L dwarfs. We find that the decline in both X-rays and Hα roughly follows L X ,Hα /L bol ∝ 10 −0.4×(SP−M6) for SP M6. In the radio band, however, the luminosity remains relatively unchanged from M0 to L4, leading to a substantial increase in L rad /L bol . Our survey also provides the first comprehensive set of simultaneous radio/X-ray/Hα observations of ultracool dwarfs, and reveals a clear breakdown of the radio/X-ray correlation beyond spectral type M7, evolving smoothly from L ν,rad /L X ≈ 10 −15.5 to ∼ 10 −11.5 Hz −1 over the narrow spectral type range M7-M9. This breakdown reflects the substantial reduction in X-ray activity beyond M7, but its physical origin remains unclear since, as evidenced by the uniform radio emission, there is no drop in the field dissipation and particle acceleration efficiency. Based on the results of our survey, we conclude that a further investigation of magnetic activity in ultracool dwarfs will benefit from a two-pronged approach: multi-rotation observations of nearby known active sources, and a snapshot survey of a large sample within ∼ 50 pc to uncover rare flaring objects. 10 The FeH Zeeman broadening technique leads to fields of 3.9 kG for EV Lac, 2.9 kG for AD Leo, and > 3.9 kG for YZ CMi (Reiners & Basri 2007), while the ZDI technique leads to much weaker fields of 0.5 − 0.6 kG, 0.2 kG, and 0.55 kG for the three objects, respectively (Morin et al. 2008).

En efecto, Schmitt había hecho notar que tanto el nacionalsocialismo como el partido comunista alemán no compartían los valores expresados en la constitución y todo esto representaba un peligro para la república misma en el caso que algunos de estos dos partidos llegaran a convertirse en mayorías parlamentarias.…”

J’accuse…! Algunas consideraciones acerca del compromiso nacionalsocialista de Carl Schmitt

Pese a los enormes esfuerzos que han hecho renombrados filósofos políticos e historiadores intelectuales por estigmatizar el estudio de la obra de Carl Schmitt, el interés por el razonamiento político-jurídico schmittiano ha logrado resistir a un punto tal que, hoy en día, cualquier interesado por la filosofía política o jurídica difícilmente pueda resistir la tentación o la necesidad de explorar la obra y el pensamiento schmittiano. Frente a este panorama, en esta ocasión me gustaría ofrecer algunas razones para sostener que la célebre y breve implicación política de Schmitt con el nacionalsocialismo (1933-1936), desde cierto punto de vista, debería quedar al margen o, en el mejor de los casos, considerarse una cuestión incidental para aquellos que se sientan interesados por el razonamiento político o jurídico schmittiano en stricto sensu. A tal efecto, luego de llevar adelante unas breves consideraciones sobre la trayectoria de la reputación de Carl Schmitt, quisiera ofrecer cuatro ejemplos que ilustran algunas buenas razones para creer que la teoría política y jurídica de Schmitt corre por un carril paralelo a las consideraciones biográficas y, por lo tanto, quisiera tratar de contrarrestar la idea según la cual existe una conexión directa o necesaria entre sus desacertados compromisos políticos y el valor que, eventualmente, puede llegar a tener su razonamiento político y jurídico.
