FP Photometry

Milisa Jettkandt & Matthias Kilb During our advanced lab course, we were able to use the TURMX remote oberservatory to observe the pulsating variable GSC 04135-00504 over the night from the 5th to 6th of January 2023 (CET). Muniwin and Mathematica were used for the photometry and curve fitting as […]

Frederik Krenzer & Jonathan Laux In our observation and investigation of the variable star V 0750 Aur in the constellation Auriga (see figure 1) on december 1st 2022, we could detect not one, but at least two different pulsation periods which we calculated to be 0.0678 d (97.6 minutes) and […]

Pierre Knötzele & Dominic Rodemer During the advanced lab course of the Department of Physics at TU Darmstadt, a variable star was to be observed for the experiment “Photometry in Astrophysics”. The star ASASSN-V J235154.14+381726.8 in the constellation Andromeda was chosen. The TURMX telescope was programmed for automatic recording in […]

Mark Bergmann & Konrad Weber Using the TURMX observatory in summer of 2022, we were able to observe pulsating stars in the constellation of Lyrae. This region of the night sky was chosen as it stood in zenith around midnight for the observatory in spanish Extremadura during the date of […]

Patrick Sekyra & Björn Sievers Due to the lab course “Fortgeschrittenenpraktikum” at TU Darmstadt we had the opportunity to use the universities remote observatory TURMX. One object – ZTF J065743.32+233712.8 – was chosen by us to observe in the night of the 13th of February in 2021, while the other […]

Michelle Müller & Christoph Rützel In the context of the advanced lab courses (Fortgeschrittenenpraktikum) we observed a star of our choice throughout one night. The chosen star’s name is ZTF J000116.54+543024.7, it is located within the Cassiopeia constellation. In photometric examinations it is often more convenient to observe the relative […]

Marietta Coelle and Yannik Atzbach We planned our observation under very unfavourable conditions: Not only we had to deal with full moon and decided to observe an exoplanet transit, which restricts the possible observations to a few time windows, but also the hourly changing weather forecast predicted heavy clouds and […]

Patrick Falk & Clemens Nickel During the photometry experiment we could observe the brightness variation caused by the exoplanet CoRoT-18b and the variable star RV Ari of the Aries-constellation in the night of the 9th and 10th of November 2020. We were also given the data of another exoplanet Qatar-4b […]

Julian Schulze & Aleksandar Vučković In the context of the physics lab course ”Photometry in Astrophysics”, we studied the variable star BN Tri, a part of the constallation Triangalum located in the northern sky. A variable star is a star whose brightness changes over time, in contrast with the usual […]

Thierry Kaldenbach & Carl Georg Boos Thanks to the Fortgeschrittenen Praktikum we were able to oberserve variable stars through a night. The chosen star NP-Lyn is located in the Lynx constellation. The observation was done the night of the 20th January, 2020. Due to many clouds the telescope shut down […]

Lisa Wagner & Cedric Wenz Photometry in astrophysics is a means to evaluating the brightness of an astronomical object, which is measured in the historical unit magnitude. Since it is much easier to measure a differential rather than an absolute brightness, the observed object is often compared to stars that […]

Gerrit Leck & Jan Kuske On November 18th 2019 we were the first group of students to conduct the new FP-experiment “Photometry in Astrophysics”. We observed several variable stars and exoplanet transits using differential photometry. Here we present extracts of our results. In the night from 23rd to 24th November […]
