Astro2020 Science White Paper Unlocking the Secrets of Late-Stage Stellar Evolution and Mass Loss Through Radio Wavelength Imaging
Astro2020 Science White Paper Unlocking the Secrets of Late-Stage Stellar Evolution and Mass Loss through Radio Wavelength Imaging Thematic Areas: Planetary Systems Star and Planet Formation Formation and Evolution of Compact Objects Cosmology and Fundamental Physics 7 Stars and Stellar Evolution Resolved Stellar Populations and their Environments Galaxy Evolution Multi-Messenger Astronomy and Astrophysics Principal Author: Name: Lynn D. Matthews Institution: Massachusetts Institute of Technology Haystack Observatory Email: [email protected] Co-authors: Mark J Claussen (National Radio Astronomy Observatory) Graham M. Harper (University of Colorado - Boulder) Karl M. Menten (Max Planck Institut fur¨ Radioastronomie) Stephen Ridgway (National Optical Astronomy Observatory) Executive Summary: During the late phases of evolution, low-to-intermediate mass stars like our Sun undergo periods of extensive mass loss, returning up to 80% of their initial mass to the interstellar medium. This mass loss profoundly affects the stellar evolutionary history, and the resulting circumstellar ejecta are a primary source of dust and heavy element enrichment in the Galaxy. However, many details concerning the physics of late-stage stellar mass loss remain poorly understood, including the wind launching mechanism(s), the mass loss geometry and timescales, and the mass loss histories of stars of various initial masses. These uncertainties have implications not only for stellar astrophysics, but for fields ranging from star formation to extragalactic astronomy and cosmology. Observations at centimeter, millimeter, and submillimeter wavelengths that resolve the radio surfaces and extended atmospheres of evolved arXiv:1903.05592v1 [astro-ph.SR] 13 Mar 2019 stars in space, time, and frequency are poised to provide groundbreaking new insights into these questions in the coming decade. -

NEWS FEATURE What’s next for the IPCC? AMANDA LEIGH HAAG Now that the Intergovernmental Panel on Climate Change has spoken more clearly than ever — and policymakers are listening — it may be time to take a new direction. Amanda Leigh Haag reports on suggested ways forward. hen the Intergovernmental Panel on Climate Change (IPCC) W was awarded the 2007 Nobel Peace Prize together with former US vice president Al Gore in October, it was a crowning moment on an already stellar year for the climate-change icon. Th e release of the IPCC’s Fourth Assessment Report (AR4) in early 2007 propelled the international body’s acronym to the status of a household name and reinforced its role as the defi nitive authority on climate change. Th e most recent report’s message was not dissimilar to those of the preceding three reports since 1990, but it came through in richer detail and with greater degrees of confi dence and consensus. Th e biggest diff erence was that this time the social climate seemed poised to receive it. “One of the reasons the Fourth Assessment was so eff ective was that the world was ready to hear it,” says Michael Oppenheimer, a climatologist PHOTOS PA at Princeton University in New Jersey and a lead author on AR4. But many are wondering what the IPCC Chairman Rajendra Pachauri, left, and United Nations Secretary-General Ban Ki-moon show the new foremost authority on climate change can synthesis report at a press conference. Scientists are now discussing what the focus and scope of future IPCC achieve from here. -

HAL archives-ouvertes.fr | CCSD, April 2020. Evolutionary processes transpiring in the stages of lithopanspermia Ian von Hegner Aarhus University Abstract Lithopanspermia is a theory proposing a natural exchange of organisms between solar system bodies as a result of asteroidal or cometary impactors. Research has examined not only the physics of the stages themselves but also the survival probabilities for life in each stage. However, although life is the primary factor of interest in lithopanspermia, this life is mainly treated as a passive cargo. Life, however, does not merely passively receive an onslaught of stress from surroundings; instead, it reacts. Thus, planetary ejection, interplanetary transport, and planetary entry are only the first three factors in the equation. The other factors are the quality, quantity, and evolutionary strategy of the transported organisms. -

Reducing Black Carbon May Be Fastest Strategy for Slowing Climate Change
Reducing Black Carbon May Be Fastest Strategy for Slowing Climate Change ∗ IGSD/INECE Climate Briefing Note: 29 August 2008 ∗∗ Black Carbon Is Potent Climate Forcing Agent and Key Target for Climate Mitigation Reducing black carbon (BC) may offer the greatest promise for immediate climate mitigation. BC is a potent climate forcing agent, estimated to be the second largest contributor to global warming after carbon dioxide (CO 2). Because BC remains in the atmosphere only for a few weeks, reducing BC emissions may be the fastest means of slowing climate change in the near-term. 1 Addressing BC now can help delay the possibility of passing thresholds, or tipping points, for abrupt and irreversible climate changes, 2 which could be as close as ten years away and have potentially 3 catastrophic impacts. It also can buy policymakers critical time to address CO 2 emissions in the middle and long terms. Estimates of BC’s climate forcing (combining both direct and indirect forcings) vary from the IPCC’s estimate of + 0.3 watts per square meter (W/m2) + 0.25,4 to the most recent estimate of .9 W/m 2 (see Table 1), which is “as much as 55% of the CO 2 forcing and is larger than the forcing due to the other 5 greenhouse gasses (GHGs) such as CH 4, CFCs, N 2O, or tropospheric ozone.” In some regions, such as the Himalayas, the impact of BC on melting snowpack and glaciers may be 6 equal to that of CO 2. BC emissions also significantly contribute to Arctic ice-melt, which is critical because “nothing in climate is more aptly described as a ‘tipping point’ than the 0° C boundary that separates frozen from liquid water—the bright, reflective snow and ice from the dark, heat-absorbing ocean.” 7 Hence, reducing such emissions may be “the most efficient way to mitigate Arctic warming that we know of.” 8 Since 1950, many countries have significantly reduced BC emissions, especially from fossil fuel sources, primarily to improve public health, and “technology exists for a drastic reduction of fossil fuel related BC” throughout the world. -

Germans are proud of their country’s reputation for environmental awareness and progressive green legislation, and not without justification. Over the last thirty years, Germany has led the way in reducing pollution from industry, transport and domestic heating, promoting recycling and reducing the volume of waste, decoupling economic growth from resource consumption and carbon emissions, and generally meeting the environmental challenges associated with population growth, urbanization and industrialization. The OECD called the country a ‘laboratory for green growth’ in 2012 and praised its ‘proactive role in environmental policy within the EU and internationally’. Its energy policy in particular had ‘a beacon-like character for many other countries around the world’ (see Uekötter, ch. 1). The Green Party has governed at regional level and, in coalition with the Social Democrats, formed the federal government between 1998 and 2006. More importantly, many of its policies have been adopted by other parties since the 1980s and passed into legislation. -

Today is May 16th, 2019. Thanks, Steve Chen, for coming to continue your oral history. I'm Marguerite Hancock with Mark Weber interviewing you on behalf of the Computer History Museum. Chen: Great. Hancock: We had such a great conversation last time. We'd like to continue where we left off, and we were just talking about pitching to Sequoia-- Chen: Right. Hancock: And there was a lot of strong interest in you and you were thinking about who you would like to work with as an investor. And I had asked you whether you knew about, or if you still had your pitch deck and you said you knew it was out there somewhere, so we found it. Chen: Yeah. Hancock: And for people really trying to understand the essence of YouTube. Chen: Yeah, yeah. Hancock: I would like to ask you if you would be willing to walk through those initial pages and tell us what you were thinking about as you made the pitch. Chen: Sure. Hancock: And then also any comments now in retrospect. Has your vision changed? Chen: Right. Hancock: Reflecting back, would you have pitched it any differently? You know and I'll just hand this if you want to refer to it along the way. Chen: Well, it was great that you found this because this kind of a Flashback to what is it, 14 years ago? As I was reading this last night and the email attachment, just about every page was almost a chapter in a new novel. -
Viruses, ET and the Octopus from Space: the Return of | Cosmos 26/04/2018, 4:37 AM
Viruses, ET and the octopus from space: the return of | Cosmos 26/04/2018, 4:37 AM Viruses, ET and the octopus from space: the return of panspermia A major paper revives the oft-mocked theory that life on Earth began in a rain of cosmic microbes. Stephen Fleischfresser reports. The search for ET, say researchers, could start and end with the octopus. CREDIT: VIZERSKAYA/GETTY IMAGES The peer-reviewed journal Progress in Biophysics and Molecular Biology recently published a most remarkable scientific paper[1]. With 33 authors from a wide range of reputable universities and research institutes, the paper makes a seemingly incredible claim. https://cosmosmagazine.com/biology/viruses-et-and-the-octopus-from-space-the-return-of-panspermia Page 1 of 14 Viruses, ET and the octopus from space: the return of | Cosmos 26/04/2018, 4:37 AM A claim that if true, would have the most profound consequences for our understanding of the universe. Life, the paper argues, did not originate on the planet Earth. The response? Near silence. The reasons for this are as fascinating as the evidence and claims advanced by the paper itself. Entitled Cause of the Cambrian Explosion – Terrestrial or Cosmic?, the publication revives a controversial idea concerning the origin of life, an idea stretching back to Ancient Greece, known as panspermia. The scientific orthodoxy concerning the origin of life is called abiogenesis[2]. This suggests that at some point in the earth’s early history, conditions were favourable for the creation of complex organic chemistry that, in turn, led to the self-organisation of the first primitive life forms.
