TOI 564 b and TOI 905 b: Grazing and Fully Transiting Hot Jupiters Discovered by TESS

We report the discovery and confirmation of two new hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS): TOI 564 b and TOI 905 b. The transits of these two planets were initially observed by TESS with orbital periods of 1.651 and 3.739 days, respectively. We conducted follow-up observations of each system from the ground, including photometry in multiple filters, speckle interferometry, and radial velocity measurements. For TOI 564 b, our global fitting revealed a classical hot Jupiter with a mass of MJ and a radius of RJ. Also a classical hot Jupiter, TOI 905 b has a mass of MJ and radius of RJ. Both planets orbit Sun-like, moderately bright, mid-G dwarf stars with V ∼ 11. While TOI 905 b fully transits its star, we found that TOI 564 b has a very high transit impact parameter of, making it one of only ∼20 known systems to exhibit a grazing transit and one of the brightest host stars among them. Therefore, TOI 564 b is one of the most attractive systems to search for additional nontransiting, smaller planets by exploiting the sensitivity of grazing transits to small changes in inclination and transit duration over a timescale of several years

State, society and market in the aftermath of natural disasters in colonial India: a preliminary exploration

How did South Asian societies rebuild their economies following natural disasters? Based on five episodes from colonial India, this article suggests that between the mid-nineteenth and the mid-twentieth century, the response to disasters changed from laissez-faire to more state intervention. Despite this change, post-disaster rebuilding was complicated by unspecified rights to lost property, conflicting claims to property, asymmetric information between aid-givers and receivers, conflicts between agencies, lack of cooperation between gainers and losers, and in some of these examples, clashes between the colonial state and nationalist organisations

Making Matters Worse

Catastrophic disasters require additional leadership capabilities because extreme events overwhelm local capabilities and damage emergency response systems themselves. Therefore, leaders at all levels must adapt and rebuild the response system, even while they are addressing the pressing needs of the disaster itself. Leaders can minimize or maximize the effects of the trigger event(s) by their actions and competence in dealing with this especially difficult set of overlapping and, frequently, even inconsistent tasks. This case studies the effects of the Katrina-Rita hurricanes on New Orleans and systematically examines how poor leadership-lacking a series of critical competencies required in extreme conditions-can maximize catastrophic events. © 2008 Sage Publications
