Once in a lifetime star explosion: T Coronae Borealis

Once in a lifetime star explosion: T Coronae Borealis

Lecture in English

Dr. Ioannis Kamaretsos (Munich Public Observatory)

Friday, 12 July 2024, 8 p.m.
Venue: Volkssternwarte München, Rosenheimer Str. 145h

T Corona Borealis is a well-known binary star system in which luminous explosions have occurred twice in the last two hundred years. These explosions, known as nova outbursts, are thought to occur at regular intervals. It is predicted that anytime this year it will go from its current very low brightness to an outburst visible to the naked eye, roughly equaling the apparent brightness of Polaris. In this talk we will discuss the nature of this phenomenon, the physical properties of the system, the accuracy of the prediction as well as how it can be observed. Following the lecture, we will use the telescopes on the roof to observe the early summer constellations. Tips will be given on how to quickly detect the nova, should it occur.

 

Unlocking a sea secret: the Antikythera Mechanism

Unlocking a sea secret: the Antikythera Mechanism

Lecture by Dr. Markos Skoulatos (TU Munich) – in English

Friday, 7 June 2024, 8 p.m.

Without any doubt, the oldest computer of mankind, known as the Antikythera Mechanism, is the greatest technological achievement of antiquity. A century was necessary in order to reveal its secrets. What is it though, that inspires until now four generations of scientists?
In this talk, we will navigate from its discovery by sponge divers, up to the latest word of modern technology in order to solve its puzzle. I will analyse its functions, epicyclic and differential gearings, the indications it gives us and how to read them. We will see how astronomy, mathematics and engineering, all come together at a small portable mechanical device. At the end, there will be an opportunity to see from close my real model reconstruction. Our purpose is to familiarise with this “mysterious” construction as well as to individually discover what it is that inspires, still, despite 2 millennia from its original construction.

The trail to the origin of life

The trail to the origin of life

Lecture by Dr. E. Bianchi (Vera Rubin Fellow at the Excellence Cluster ORIGINS) – in English

Friday, 12 April 2024, 8 p.m.

How did our planet form? Why is there life on Earth? Each of us has asked these questions at least once in our lifetime. Planets are the product of a cosmic recipe that begins with a cold and dark cloud and ends with a star and its planetary system. As of today, astronomers detected more than 5000 planets orbiting around stars that are not our own Sun. Although we are still not able to detect evidences of life on other planets, upcoming space missions will make it achievable in the near future. Terrestrial life is based on relatively small molecules containing carbon atoms, oxygen, hydrogen and nitrogen.
During the presentation, I will talk about the origins and formation of organic molecules in space and discuss their potential role in seeding life on a young Earth.

 

Problems in Astronomy & Astrophysics

Problems in Astronomy & Astrophysics

Lecture in English

Dr. Ioannis Kamaretsos (Munich Public Observatory)

Monday, 18 March 2024, 7 p.m.
Venue: Volkssternwarte München, Rosenheimer Str. 145h

I will be presenting a series of puzzles from the fields of astronomy and astrophysics, ranging from easy to intermediate, ending in a few competitive puzzles. These are not your usual „pub quiz night“ riddles, but appeal to physical intuition. Let’s go through the items together to gain a deeper understanding of our cosmos as well as an insight into how astronomers work. Black holes, the search for extraterrestrial life, planetary motions, gravity, observational phenomena and other topics will be covered. Please don’t forget your little personal notebooks.
The lecture will be followed by a round of telescope observations on the roof.

 

 

The Twin Paradox and its resolution

The Twin Paradox and its resolution

Lecture in English

Boris Lohner (Munich Public Observatory)

Tuesday, 12 March 2024, 7 p.m.
Venue: Volkssternwarte München, Rosenheimer Str. 145h

Explanations of the twin paradox sometimes give the impression that special relativity is defective and that this „defect“ requires general relativity to be „repaired“ – or give the impression that time dilation is not real but a mere effect of observation. In this talk it is shown how the twin paradox can be resolved in a consistent way while staying within special relativity.

The Dance of Binary Stars – About ‚vampire stars’, binary black holes, and being squeezed by gravitational waves

The Dance of Binary Stars –  About ‚vampire stars’, binary black holes, and being squeezed by gravitational waves

Lecture by Prof. Dr. Selma E. de Mink (Max Planck Institute for Astrophysics) – in English

Friday, 8 March 2024, 8 p.m.

When seeing stars in the night sky over Munich on a clear evening, you may be able to pick out some of the constellations. Those with sharp eyes may even notice the stars have subtly different colors, such as the red supergiant star Betelgeuse that makes the shoulder of the Orion constellation. Some can even be seen to be double, such as Mizar and Algol in the big dipper (großer Wagen) that forms a multiple-star system.

In this talk, I would like to share some of the latest advances in our understanding of stars and binary systems. What does a star like Betelgeuse look like if you were close? – I will show movies from our latest computer simulations of the boiling surface. What is a binary system? – I will explain why astronomers now think that almost no star is alone. How are the lives of binary stars different? – I will show what a so-called vampire system is, where one star becomes younger by ‘eating’ the outer layers of its companion. What are gravitational waves and what does that have to do with binary stars? – Come to my talk and I hope to give you a taste of all these exciting new insights.

The talk will be in English, but the speaker will be happy to take any questions in German.

 

The dawn of high energy neutrino astronomy

The dawn of high energy neutrino astronomy

Lecture by Prof. Dr. Elisa Resconi (TU München) – in English

Friday, 24 November 2023, 8 p.m.

The IceCube Neutrino Observatory has been at the forefront of neutrino astronomy for the past decade, detecting high-energy neutrinos beyond Earth’s atmosphere. This presentation will showcase IceCube’s recent findings as well as future projects like the P-ONE in the Pacific Ocean.
